Abstract Introduction The conventional model of web application development separates frontend and backend responsibilities into different teams, skillsets, and codebases. Frontend developers manage UI and client-side logic, while backend developers handle server-side processing, API creation, data storage, and security enforcement. However, this division can lead to longer development cycles, coordination challenges, and duplicated logic across layers. A new paradigm is emerging—one in which frontend developers can declaratively define backend logic using frontend tools and syntax. This shift is enabled by modern platforms that offer serverless scalability, secure permission management, and efficient request/response handling under the hood. This approach doesn't eliminate the need for ba…  ( 5 min )

Introduction to UDF and Vector UDF in Spark 3 In Spark 3, the advent of vectorized UDFs (User Defined Functions) has created a significant advancement in how operations on DataFrames can be efficiently executed. Understanding the differences between traditional UDFs and the newer vectorized UDFs is crucial for optimizing performance in big data processing. What are User Defined Functions (UDFs)? Traditional UDFs User Defined Functions, commonly referred to as UDFs, are functions written by users to extend the functionality of Spark. They allow you to perform custom operations on DataFrames and Datasets. For example, if you want to apply a complex transformation that is not available out-of-the-box in Spark, a UDF can be created in languages like Scala or Python. How Traditional UDFs Work T…  ( 5 min )

Introduction When working with Entity Framework Core (EF Core) in C#, managing relationships between entities is crucial. In this scenario, we have a case where a department can have multiple users, and when a user is assigned a new department, we need to ensure the previous department is deleted if it has no users left. This is a common requirement in applications that handle organizational structures. Why the Department Query Might Not Reflect Updates In your situation, you are attempting to update a user's department and then immediately check if the previous department has users left. You notice that even though the update reflects in the database, the department load returns stale data. This issue can arise due to EF Core’s change tracking behavior and how it interacts with the databa…  ( 5 min )

Libuv describes itself as a multi-platform support library with a focus on asynchronous I/O. It is widely used in many web servers (e.g., Kestrel) and runtimes such as Node.js and Python (via uvloop). As of Zig 0.14.0, there is no native async I/O, so you must work directly with threads or create your own async API using OS primitives like epoll or kqueue. In many cases, you would likely choose a cross-platform library rather than implementing your own async API. That’s where using libuv, libevent, or libxev (written in Zig) becomes useful. This guide will show you how to use libuv from your Zig project. I’ll start with a basic Zig project to demonstrate how this works. It will be a simple app that runs some timers. We’re going to use the package from github.com/allyourcodebase/libuv to bu…  ( 5 min )

An open-source project called Deep-Live-Cam is gaining traction on GitHub — and for good reason. With just a single still image, it can mimic anyone’s face in a live video call. In real-time. Running locally. No cloud required. The implication is clear: you can no longer trust a video call at face value. So here’s the question: how do we verify identity in a world where faces can be forged on demand? While many react with fear or disbelief, I see only one viable answer: digital signatures. For years, I’ve been saying: we should encrypt everything — files, messages, infrastructure. But now, that’s not enough. We need to start signing everything. Digital signatures ensure authenticity. They prove that something really came from who claims to have sent it and hasn’t been tampered with. We already sign emails, source code, and software packages. Why not apply the same principle to real-time streams? Imagine a video call cryptographically signed with the speaker’s GPG key. Even if the face looks convincing, if the signature doesn’t verify, you know something’s off. I sign every HTML page on my personal website with my GPG key. Not because I’m paranoid — but because I believe security should be a mindset. Don’t trust. Verify.  ( 3 min )

If you're learning C# or .NET development, you might encounter this frustrating error: One or more errors were encountered while creating project ConsoleApp3. The generated project content may be incomplete. The SDK 'Microsoft.NET.Sdk' specified could not be found. I faced exactly this issue during my early days learning C#. After multiple attempts, I finally found a solution that worked reliably for me: The root cause appears to be that the official .NET SDK installer sometimes doesn't correctly set up the SDK on your system. Even after installation, the command dotnet --list-sdks might return an empty list, which indicates the SDK isn't properly recognized by your system. Here's what worked for me: Download the Binaries Manually: Go to the official .NET SDK downloads page. Instead of downloading the installer, choose the "Binaries" option. This will give you a .zip file containing the SDK files directly. Extract and Copy Files: Extract the downloaded .zip file to a temporary location. Replace SDK Contents: Navigate to: C:\Program Files (x86)\dotnet\ Delete or back up existing contents, then paste the newly extracted SDK binaries into this folder. Verify Installation: Open a new Command Prompt or PowerShell window and run: dotnet --info You should now see details about the SDK and runtime versions installed. This solution manually ensures that the SDK files are correctly placed and recognised by your system, bypassing the potential issues caused by the automated installer. If you're still experiencing issues after following these steps, consider checking your environment variables to ensure C:\Program Files (x86)\dotnet\ is correctly listed in your system PATH.

gRPC (Google Remote Procedure Call) is a high-performance, open-source framework for making remote procedure calls. Unlike traditional REST APIs that use HTTP/1.1 and JSON, gRPC leverages HTTP/2 and Protocol Buffers for more efficient communication between distributed systems. This modern approach offers significant advantages in terms of performance, type safety, and code generation capabilities. When working with gRPC, you need to understand the fundamental components and workflow that differentiate it from other API communication methods. The process begins with defining your service interface using Protocol Buffers (protobuf) in a proto file, which serves as a contract between client and server. This definition is then compiled into language-specific code that handles all the underlyin…  ( 5 min )

A week ago, I did something slightly unhinged: reads, modifies, and rewrites itself while it's running. Not some weird meta joke — I mean the actual .js file mutates its own content based on how it's used. And yes... it works. I was tired of manually tracking how often certain functions were used. I could’ve used telemetry, logging, whatever. But I thought: "What if the code just kept track of itself — in itself?" Imagine a function…  ( 6 min )

Introduction Have you ever faced an unexpected behavior in your Bash scripts, particularly regarding loops? In this article, we will delve into a common issue with the continue statement in Bash, as illustrated by your provided script. You're correct in observing that the continue statement should skip the remaining commands in the loop and jump to the next iteration. So, why isn’t it working as expected in your case? Understanding the Issue The primary reason the continue statement may not be functioning as you expected lies in the structure of your loop and the way Bash interprets commands. A common mistake is how command substitutions and pipes are handled in Bash scripts. When you use a pipe (|), the commands are run in separate subshells. This means the continue statement is scoped to…  ( 4 min )

As software engineers, our job isn't just writing features or fixing bugs. We're responsible for improving the processes around software and help teams move faster, safer, and more consistently. That means asking questions like: Can we reduce repetitive tasks? Can we encode best practices so new team members don't guess? Can we lower the mental load of starting new features? For Angular projects, Schematics is one of the best tools to operationalize these improvements. It lets you automate architecture, encode standards, and enforce patterns. A schematic in Angular is a set of instructions that tells the Angular CLI how to generate or transform code. Think of it as a script that can: Create new files using templates. Update existing code (e.g. add a component to a module). Enforce consiste…  ( 4 min )

Hi devs — I recently launched a platform called aimodeling.me, and I’d love to share what it does, how it works, and why I built it. In short, it lets you create a realistic AI model of yourself — your own "digital twin" — from just a few selfies. After that, you can generate endless photorealistic images of you in any scenario, outfit, or setting you can describe. We’re all used to AI image generators now, but most of them produce generic faces or imaginary people. I thought: what if we flipped that? What if you could put yourself in those scenes? Professional photoshoots are expensive, awkward, and static. I wanted a way to generate high-quality, personalized photos for myself (for social media, bios, content creation, etc.) without constantly needing to step in front of a camera. So I b…  ( 4 min )

Working in Japan under the constraints of a work visa means there’s really not much you can do besides your day job. About the only other option is saving money and investing through NISA... Even if your company allows side jobs, you still need to apply for “Permission to Engage in Activity Other Than That Permitted Under the Status of Residence,” and possibly register and communicate with the authorities. Just thinking about all that paperwork makes me not want to bother. After all, the main goal is to build a life where I can live long-term in a place I truly want to be — for me, that’s Japan. So in reality, my daily life basically revolves around working and studying to prepare for a career move. I won’t deny that this kind of routine gets a bit dull over time. I just want a little more freedom, especially since both language learning and job hunting take so much time. Anyway, I need to hit my goal as soon as possible so I can finally enjoy the freedom I want in Japan!  ( 3 min )

Abstract Alzheimer's disease (AD) represents a significant global health challenge. This paper proposes an experimental approach for early AD detection using Electroencephalography (EEG) signals processed through an innovative deep-learning architecture. I suggest a channel-frequency-based attention model that effectively captures spectral features across different brain regions. This model uses depthwise convolutions, squeeze-and-excitation blocks, and spatial dropout regularization to efficiently learn patterns within EEG data. The dataset has 19-channel EEG recordings from subjects with Alzheimer's, healthy controls, and frontotemporal dementia. The model shows 83.81% accuracy, which tells us about its potential.

This blog is for those, who want to start their first full stack development project but not have enough idea about how to start. I will try to cover some of the things that you should follow for make your first project journey more smooth. Folder Structure: The first thing you might face difficulties is creating and understand the folder structure. It may vary by project to project, but their are some common concept like creating 2 separate folder, one for frontend and other one is for backend. Inside each folder you will have multiple folders. For backend you will have folders like models, services, api endpoints etc (based on your requirements) . And for frontend, you will have src folder inside which you will find components, assets, pages, api, utils etc folders (if you are using React). fullstack-project/ Make sure you must write code as clean as possible. It is a good practice. You should right the logics more efficient way. You can also create a folder for a particular module and inside that you can create multiple files so that anyone can easily find the code written for a specific purpose. It will reduce cognitive complexity. Another thing you should remember that don't make a function so large with so much logics in a single function, rather use multiple functions, each for a particular logic and use them in that function. Before writing any routes, you should always first do some floor planning like how this routes is going to use, how many times this routes will be called. It is completely necessary when you are going to deploying the project into the server. Because the more api needs to call from backend, the more it will take time to load and resulting the website slow. Wish a happy journey for your first project 😄 and share if you find this post helpful.  ( 4 min )

Have you ever felt like you're fighting with your own APIs? As a backend developer, I sure did... until I learned to stop debugging through the frontend and start talking directly to my APIs instead.

You can read the intro here: Let’s say you join a new team and find this in one of the core API controllers: [HttpPost("updateOrder")] public async Task UpdateOrder([FromBody] OrderDto order) { var updatedOrder = await _orderService.Update(order); return Ok(updatedOrder); } At first glance, it seems reasonable. It compiles. It works. It even passes QA. But if this looks fine to you — keep reading. This kind of code is deceptively simple. In fact, it’s a perfect example of how bad design doesn’t look broken, until it is. Under the surface, this endpoint is full of subtle flaws that will confuse consumers, pollute your Swagger docs, and slow your team down over time. Let’s unpack what’s wrong, and more importantly, how to fix it. Let’s break it down: You're updatin…  ( 7 min )

Most programmers will agree that state management is a pain (in the head). Which is why they shy away from it at every opportunity. Languages, functional or OOP, make no difference - if state is only ever passed around to and from the database, it's all practically stateless in my book. In the industry-accepted programming model (clean model, layered model, hexagonal model) state management (database I/O) is on the outer layer - why? Oh, because you don't actually operate on entities that you store, you operate on transient entities derived from them. This abstraction is necessary, because in most modern languages state is carried by objects - and you can't store objects, only things derived from them. Be it rows in tables, or at least whole aggregates in NoSQL DBs. Actual object state can…  ( 4 min )

Counting boolean flags in a SQL table can be a common task, especially when you're trying to evaluate multiple conditions simultaneously. However, using multiple queries can be inefficient.

I've been developing PHP applications for over 15 years now, working with various PHP frameworks. Throughout this journey, I've witnessed many projects that began as monoliths eventually need to evolve into microservices. That's when interesting architectural challenges emerge. While I'd successfully used RoadRunner (RR) with Spiral and Symfony before, I wanted to bring these same capabilities to my Laravel projects. Yes, Laravel Octane does provide RR integration but only for HTTP. I needed the full ecosystem of plugins that make RR truly powerful for distributed systems.

At M47 Labs, we work on many AI and cloud-native projects where secret management becomes complex — especially across environments and CI/CD pipelines. We're big fans of AWS SSM for storing configuration and secrets securely, but syncing them into .env files can be painful and repetitive. To solve this in a cleaner and more reliable way, I built a CLI tool: 👉 Envilder on GitHub Envilder reads a mapping file that links environment variable names to AWS SSM parameter paths. .env file. Your param-map.json might look like this: { "DB_HOST": "/my-app/dev/DB_HOST", "DB_PASSWORD": "/my-app/dev/DB_PASSWORD" } Run: envilder --map=param-map.json --envfile=.env And you get: DB_HOST=mydb.cluster-xyz.rds.amazonaws.com DB_PASSWORD=supersecret You can also use different AWS CLI profiles: AWS_PROFILE=staging envilder --map=param-map.json --envfile=.env This small tool makes a big difference when: 🧑‍💻 Onboarding new team members: no more “what’s the DB password?” 🔄 Keeping environments in sync: any change in SSM is reflected across the team ⚙️ CI/CD pipelines always up-to-date: e.g. GitHub Actions, CodeBuild, GitLab 🧼 Centralized configuration: avoid duplication and keep secrets in one secure place 🧭 Supports multiple AWS profiles: ideal for multi-account or multi-env setups Works with SecureString and plain parameters CLI-first, fast, and script-friendly Compatible with any CI system Supports static values and fallbacks AWS profile support (AWS_PROFILE) npm install -g envilder Or: envilder --map=param-map.json --envfile=.env --profile=aws-account It’s still an early-stage project, but already helpful in several real-world teams.

Stop Guessing: Understand JavaScript Equality the Right Way When you start working with JavaScript, one of the first things you notice is how flexible it feels. You can assign different types of values to the same variable and JavaScript won’t complain. This flexibility is great—but it can also lead to unexpected bugs, especially when you're comparing values or checking if something is "true" or "false." Let’s break down some of these concepts in a beginner-friendly way so you can write safer and more predictable JavaScript code. In JavaScript, you don’t need to declare the type of a variable. For example: let x = 5; // x is a number x = "hello"; // now x is a string x = true; // now x is a boolean This is called loose typing—a variable can hold any type of data, and JavaS…  ( 6 min )

This is a submission for the Amazon Q Developer "Quack The Code" Challenge: Crushing the Command Line Some AI-powered coding assistants already support code reviews, but most of them tend to review an entire workspace or just the currently open file. In real-world scenarios though, code reviews are often based on pull requests—where we only need to review changes between two branches, not the whole project. For example, reviewing just the differences between a hotfix branch and main. That got me thinking: wouldn’t it be great if an AI coding assistant could handle that kind of focused review? At least as a first layer—giving us a detailed AI-generated review of the changes before we jump in manually. That way, human reviewers can just focus on refining things further instead of starting from scratch. One of Amazon Q Developer’s cool features is its CLI and MCP (Model Context Protocol) support. So I thought: why not use Amazon Q CLI to compare two branches—say, hotfix and main—and then have it go through the changed files one by one, review them, and finally compile the feedback into a single file using MCP as well? That way, whoever’s reviewing the PR can read the AI’s review first before doing their manual checks. Code Repository Code Review with Amazon Q Developer CLI I used Amazon Q Developer as the first layer of code review—comparing one branch to another, like from hotfix to main. This helps make the review process smoother, more effective, and scalable—especially when combined with a follow-up manual review. What makes it even more exciting is that Amazon Q Developer can both generate code and review it too. Pretty handy, right?  ( 4 min )

-- Loose Equality allows different kinds to become an equal kind. I've been feeling, blogposts treat loose equality in JavaScript as a kind of black magic because people do not master it. It isn't supposed to be esoteric magic. I am not involved in browser development but I conducted my tests with Firefox and Chrome and I read the MDN pages. You can check the examples. I say, make full potential of Javascript's capabilities, intentionally and knowingly. It can save us from some coding overhead, even when the original definition is sometimes flawed. The loose equality can make code more concise… This means, if you know the types of the operands. Therefore, the loose equality is particularly useful with TypeScript, because it can show you the types of expressions. True, even TypeScript lack…  ( 8 min )

In Part 1, we used Kubernetes Ingress to route traffic to two Go-based microservices based on specific paths. In this second part, we’ll explore advanced Ingress features.

So this week, I tried to share what I’m building on Reddit. Two posts. Two different subreddits. Both were removed instantly by Reddit’s filters. No explanation. No mod feedback. Just gone. What were the posts about? I’m building a solo project called KindredCircl — a social platform focused on belonging, privacy, and connection. No ads. No rage-bait. No surveillance. Both posts were written thoughtfully. No spam. No “buy this.” Just honesty, tech stack, and a link to a longer write-up on Dev.to. But apparently, Reddit’s automation saw all that and said: nope. Reddit is supposed to be where indie hackers hang out. Where devs build in public. Where creators share early work and get support. But what I’m realizing is: if your post doesn’t match the format the filter expects, or if you use certain words (like support, link, or solo founder), you might just get silenced. Not because of what you said — but because a bot decided you were promotional by default. I’m still building. I’m still sharing. But I’m reminded how important it is to build spaces where authentic effort isn’t treated like spam. KindredCircl is meant to be one of those spaces. And yes — it still exists, even if Reddit didn’t want to hear about it this week. If you’ve had posts removed without explanation, or felt like you’re shouting into the void, I’d love to hear your story too. Let’s be loud for each other — since these platforms clearly won’t do it for us.  ( 3 min )

A few days ago, I stumbled across an interesting blog post by Solusipse about hiding images in sound—more specifically, encoding them into the spectrogram of an audio file. It reminded me of old-school tech like dial-up modems and the ZX Spectrum, but with a modern twist. Naturally, I had to try it. Solusipse provides a Python script, spectrology.py, that takes an image and converts it into an audio waveform whose spectrogram visually resembles the image. I cloned the repo, followed the README, and ran the script, hoping for a cool output. But things weren’t so smooth. The script hit an error out of the gate.

It all started innocently enough. Back in 2009, I just wanted to port Earcut to Flash for a mini-game I was working on. And honestly? It worked — for a while. But over time, I realized that simple solutions tend to fall apart the moment you try to push them to their limits. That’s when I dove into the theory - digging through research papers, YouTube tutorials, and whatever else I could find. One of the most helpful resources was a book by A.V. Skvortsov. Eventually, I landed on the classic approach: decomposing a polygon into monotone pieces. It seemed obvious. And oh - I hit every possible wall while trying to make it work. The first big insight? Replace float with int. That alone got me almost there. But the algorithm was still fragile. Really fragile. Self-intersections, collinear edge…  ( 7 min )

Docker isn’t just about running containers. It’s about understanding how systems work, why things break, and what to do next. Most tutorials give you commands to copy paste. This guide gives you projects to learn from, backed by theory and real-world context. By the end, I’ll share a secret most Docker experts won’t tell you a way to master it faster. Let’s start. Build a Multi-Container App with Docker Compose Modern apps rely on multiple services (like a web server, API, and database). Docker Compose orchestrates these services, handling networking and dependencies. Without it, you’d manually start each container and connect them a recipe for errors. The Code: # docker-compose.yml version: '3' services: web: image: nginx:alpine ports: - "80:80" …  ( 6 min )

✍️ Introduction Throughout my experience working with clients from domains like healthcare, insurance, and legal, I often found myself curious about how certain backend document workflows functioned, especially in healthcare. While supporting these systems, I’d often get paged for incidents related to PDF pipelines: upload failures, script errors, or extraction gaps. At that stage, like many in support roles, we’re limited to handling outcomes rather than building or understanding the full solution. Over time, as we gain more experience, build trust, and make people feel confident in our abilities, we gradually get the opportunity to be part of architecture discussions and solution design conversations. But that curiosity about how these pipelines actually work — from PDF upload to raw t…  ( 5 min )

AI agents are no longer science fiction. We're moving fast toward a world where intelligent agents assist in everything from customer service and infrastructure orchestration to dev workflows and automated research. These agents aren’t monoliths—they're modular, specialized, and increasingly autonomous.

A constructor function is a special type of function used to create and initialize objects in programming, particularly in object-oriented languages like JavaScript. Think of it as a blueprint or factory for making many similar objects. Imagine you're managing a car manufacturing company. Every car you build shares the same structure—engine, wheels, color, and brand—but each one has its own values. Instead of manually building each car from scratch, you use a car-making machine (constructor function). You input values like color, brand, and engine size, and the machine builds the car for you. function Car(brand, color, engineSize) { this.brand = brand; this.color = color; this.engineSize = engineSize; } This is the constructor function.

In today's rapidly changing programming world, Rust and Zig are the hottest topics. Both modern, low-level programming languages exist mainly to address shortcomings in older systems programming languages like C and C++. But which one would you choose to learn in 2025? Is Zig a competitor to Rust, or does it remain the reigning champion? We will discuss their pros and cons and their best use cases. The Rise of a New Competitor But now, there comes a new competitor: Zig. Lightweight and flexible, it's not going unrecognized by the low-level developers with its focus on manual memory management, compile-time safety, and minimal run-time overhead. With this adoption trend, that question arises among many of how true this is: ''Is Zig a real competitor to Rust?'' Hence, in the following article, we shall compare Rust and Zig, note significant differences, and possibly help you decide on which of the two you are planning to learn in 2025. Why is Rust So Popular? 1. Memory Safety Without a Garbage Collector 2. Fearless Concurrency 3. Performance on a Par With C and C++ Rust provides zero-cost abstractions that allow a high level of expressiveness in writing programs while incurring little or no run-time overhead. In many cases, Rust is as fast as or faster than C/C++. 4. A Thriving Ecosystem and Strong Tooling Rust Uses and Applications For massively scalable applications, Rust fits the bill. The flip side of such scalability would certainly be a lot of complexity, and this is where Zig fills the void. The Minimalist Challenger: Zig Unlike Rust's expensive and stringent powers with sections for systems programming, Zig is strictly minimalist and performance-optimized with no specific automated memory management.

I’m building a project using Next.js (latest version) with Tailwind CSS and deploying it to Vercel. The issue is: all design changes (layout structure, visual style updates, etc.) show up perfectly in local development, but they don’t appear at all on the production URL after deployment. Things I’ve tried: git push to main runs without errors. Vercel deployment shows status as “Ready” with no build errors. Forced browser refresh (Ctrl+Shift+R), cleared cache, used incognito mode. Tested on multiple browsers and devices. What could prevent design changes from being reflected in production? I’d appreciate any advice or suggestions. I’ve repeated the steps multiple times and still can’t get the updated design to show live.  ( 3 min )

In the digital age where apps talk to servers, systems talk to each other, and devices sync data across continents, JSON stands tall as the standard language of communication. Simple in form but powerful in function, JSON is a foundational technology in software development, used across web, mobile, IoT, AI, databases, and cloud platforms. Let’s break down JSON from theory to real-world practice, with examples and project-level applications. JSON (JavaScript Object Notation) is a lightweight text-based format for representing structured data. Despite its name, JSON is language-agnostic, and supported natively or via libraries in virtually all programming languages. JSON Data Types: Strings: "John" Numbers: 25, 3.14 Booleans: true, false Objects: { "key": "value" } Arrays: [1, 2, 3] Null: n…  ( 5 min )

Cloud computing isn't simply a catchphrase in today's digitally first society; it's the foundation of contemporary company operations. The cloud makes speed, size, and cost-effectiveness possible for everyone from start-ups releasing mobile apps to multinational corporations overseeing operations worldwide. However, "the cloud" isn't a universally applicable answer. Different kinds of cloud services are available, depending on what you're building and how much control you desire. Let's dissect them. 1. Infrastructure as a Service (IaaS) What User Manages: What the Provider Manages: Use Cases: Examples: Ideal for: Developers and system administrators who want flexibility without managing hardware. 2. Platform as a Service (PaaS): What User Manages: What the Provider Manages: Use Cases: Examples: Ideal for: Developers who want to build applications quickly without worrying about backend setup. 3. Software as a Service(SaaS): What User manages: What the Provider Manages: Use Cases: Examples: Ideal for: End-users or businesses who want to use powerful software without installing or maintaining it. What Should You Pick? Choose Infrastructure as a Service (IaaS) if you require total control over your environment. Select PaaS if you wish to concentrate just on development. SaaS is your friend if all you need to do is use an app to get started quickly.  ( 4 min )

Understanding the Issue of Missing URL Parameter in FastAPI When using a Next.js frontend to send data to a FastAPI backend, it's important to ensure that all parameters, including files and URLs, are properly formatted and sent in the FormData. In your case, while the username and files are being received correctly by the FastAPI endpoint, the urls parameter is showing up as None, which can be quite perplexing. Let’s dive into the potential reasons why this is happening and how to resolve it. Reasons Why the URLs Parameter Might be None Incorrect FormData Structure: One common reason for receiving None in the FastAPI backend for the urls parameter could be due to the way the data is appended to the FormData in the Next.js code. If validUrls is not defined correctly or if it doesn't contai…  ( 4 min )

Legal tech is booming, but building for the legal industry comes with hidden technical, ethical, and compliance challenges..here’s what every dev should understand before jumping in. So you want to build the next AI tool that revolutionizes law? Great!!legal professionals need better, faster tools. But before you start coding your first legal document parser or compliance bot, there are real-world landmines to avoid. Legal data is often highly sensitive and subject to strict confidentiality rules (think attorney–client privilege or court-sealed documents). Scraping, storing, or even training on this kind of data without safeguards could expose you and your users to legal risk. Also, when your AI outputs a compliance decision (e.g., GDPR audit findings or AML flags), you're not just providing a "suggestion", you may be influencing legal liability. Many jurisdictions require explainability, auditability, and even human-in-the-loop systems. Legal language is dense, full of nuance, and jurisdiction-dependent. Two identical phrases may have opposite meanings depending on where and how they appear. Of course, you know there are already APIs and frameworks built for legal applications. Don’t reinvent the wheel. Legal professionals are risk-averse by design. They value clarity, documentation, and accuracy over speed. Your app’s UX must reflect that. If they can’t trust it, they won’t use it, no matter how smart it is. Are you building legal tech tools? What challenges have you run into? Drop a comment or connect—let’s push the future of legal AI forward, together.  ( 3 min )

昨天的文章介绍了使用uniapp跨平台鸿蒙应用时如何配置开发环境和运行调试项目,今天介绍一下uniapp项目目录的结构。 上面的两个文件夹pages中存放的是项目的页面，static则是存放静态资源的文件。 继续往下面看，App.vue文件打开可以看到它里面存放了项目的生命周期函数，比如项目启动、项目退出等等。 index.html相当于项目的根页面，它虽然也属于页面，但是在uniapp中通常是不需要大家修改的，因为可以看到里面有一个id是app的容器，我们在项目中写的所有代码最终都会注入到这个容器中。 Main.js是整个项目的核心入口文件，负责初始化Vue实例和全局配置 Manifest.json中存放了项目的各种配置文件，项目的名称、版本、描述、各个平台的的运行配置都在这里。 Pages.json中存放了项目中所有的页面路径和全局样式，尝试在globalStyle中的样式做一些修改，项目的全局样式就会被改变。而当新建了一个页面时，也会在这里自动注册。 最后的uni.scss文件，打开可以看到它已经给出了解释，这里是uni-app内置的常用样式变量。 以上就是uniapp项目初始化后的项目结构，还没结束，当我们运行项目后，还会新增unpackage目录，打开可以看一下是不是很熟悉，编译器把uniapp项目编译成了鸿蒙项目，这就是跨平台开发的运行原理。 以上就是对uniapp项目结构的详细解读。经历了两天的项目环境搭建和介绍，接下来的教程我们会进入到正式的跨平台开发编码环节，欢迎您持续关注。  ( 2 min )

I've embarked on a project that, although simple, has been a challenge. I've built my personal website, resume, and code visible on GitHub. This has been a bit of a challenge, because I knew my code would be visible and analyzed by recruiters. Still, I did it with love and enjoyed the experience. With it, I've had to be a software architect, content creator, project manager, developer, and SEO. Along the way, I've learned and grown. I've seen things I want to take to other projects, and the importance of following the principles of clean code, design patterns, and an architecture that's easy to scale. This project is built with Angular version 19. I use standalone components, computed properties, and effects, as well as rxResource and new features of the framework. For the UI, I used Angular Material, but minimally. The design is simple, designed so that people with visual impairments can use it without problems, balancing color contrast and good visual results. The result is my personal website, which I've been building little by little, and which I'm now sharing with you at www.antonioubedamontero.com.

Understanding Instance Counters in Ruby In the world of object-oriented programming in Ruby, ensuring that each class maintains its own instance counter is a common requirement. This article explores how to implement instance counters for classes in Ruby using class-level instance variables, as opposed to class variables which are shared among all subclasses. We will tackle the problem of accessing these counters while keeping their setters private, ensuring that they cannot be modified from outside the class hierarchy. Why Use Class-Level Instance Variables? Using class-level instance variables (like @instance_count) allows different layers of a class hierarchy to maintain their own counters. This avoids the pitfalls of class variables (denoted by @@), which are shared across all instance…  ( 4 min )

POS testing involves testing the POS application to ensure it’s ready for market use. The testing environment mimics the real-world retail scenario, and the tester will take the POS system through multiple use cases to see how it holds up to day-to-day usage. Typically, POS software testing takes place at two levels—how it runs transactions at the front end and how the systems work at the enterprise back end. There are three main parts in a POS system architecture: POS terminal: This is the place from which the POS system runs all its functions. Server: This stores all information about the retail unit, including inventory details, product prices, applicable discounts, and more. Any query generated at the main terminal gets transmitted to the server. Processing unit: This processes the req…  ( 7 min )

One of Zig’s most powerful features is its ability to run code at compile time. This enables code generation, validation, and optimizations that would be much harder (or impossible) in many other languages. In this tutorial, we’ll walk through practical examples of Zig's compile-time programming and how you can use it effectively. You can run code at compile time using comptime: const std = @import("std"); const num = comptime calculate(); fn calculate() usize { std.debug.print("Evaluating at compile time\n", .{}); return 42; } Here, calculate() is run at compile time, and num becomes a constant value. comptime Parameters Zig lets you write generic functions and types using comptime parameters: fn identity(comptime T: type, value: T) T { return value; } const result = ide…  ( 4 min )

Zig’s build system might look unfamiliar at first, but it's actually one of its greatest strengths. By using Zig itself as the configuration language, build.zig gives you full programmatic control over compiling, linking, testing, and more — without external tools or DSLs. build.zig? Every Zig project with multiple files or custom build steps uses a build.zig script. This script defines how to build your application using Zig's std.Build API. build.zig Example Here’s a simple build script for a Zig executable: const std = @import("std"); pub fn build(b: *std.Build) void { const target = b.standardTargetOptions(.{}); const mode = b.standardReleaseOptions(); const exe = b.addExecutable(.{ .name = "hello", .root_source_file = .{ .path = "src/main.zig" }, …  ( 4 min )

Introduction If you're new to Dart and want to manage data efficiently, using a class to store instances in a map is a great approach. In your case, you're trying to maintain a persistent map that holds instances of myCar, but you're encountering an issue where the map is reset every time addInfoToMap() is called. Let's explore why this is happening and how to fix it. Why is myMapOfCars Being Reinitialized? The main reason myMapOfCars is reinitialized each time is that it's defined as an instance variable (implicitly associated with each instance of the myCar class) rather than as a static variable that belongs to the class itself. Each time you create a new instance of myCar, a new myMapOfCars is created, which is why it appears empty when you call addInfoToMap(). Solution to Persist Data…  ( 4 min )

Enums and error sets in Zig offer powerful ways to model states and failures with clarity and precision. In this tutorial, we’ll cover the basics, then walk through real-world uses of both types — and how they play nicely together. Enums let you define a type with named values: const Direction = enum { North, South, East, West, }; You use them like this: const dir = Direction.North; Zig will guarantee at compile time that dir is one of the defined directions. Zig encourages exhaustive switching — the compiler checks for missing cases: switch (dir) { Direction.North => std.debug.print("Going up\n", .{}), Direction.South => std.debug.print("Going down\n", .{}), Direction.East => std.debug.print("Going right\n", .{}), Direction.West => std.debug.p…  ( 4 min )

Investors of Bitcoin Satoshi's Vision (BSV) — a hard fork of Bitcoin Cash (BCH), which itself is a hard fork of the Bitcoin (BTC) protocol, are attempting to revive a 2019 lawsuit against crypto exchange Binance for delisting the altcoin, which the litigants claim stunted the price of BSV.   According to Law360, attorneys for the plaintiffs argued that a July 2024 decision from the UK Competition Appeal Tribunal dismissing the "loss of chance" claim made against Binance for delisting the token, should be reconsidered. The litigants demanded $9 billion in damages, in the original case. The investors continue to claim that Binance's 2019 delisting of BSV and similar major exchange delistings are the primary drivers of BSV's long-term price decline and its failure to attract the investor atte…

Opinion by: Kevin Rusher, founder of RAAC It’s a volatile world out there. This year, we’ve seen stocks take a wild ride as gold has pumped and crypto has been caught somewhere in the middle. Investors have dumped risk assets and scrambled for safe havens. Gold is leading the charge. While gold is safe, it is not very hard-working. Unlike cash and treasuries, the yellow metal does not generate income. Now, more than ever, investors need to be able to earn yield on gold — particularly in the decentralized finance (DeFi) sector. The only way to make money from gold is to buy low and sell high. Most investors don’t tend to buy gold like this. That’s for good reason — over the long term, gold’s performance is typically consistent, if not without a few peaks and troughs here and there, as we h…

No matter how hard it is, we are not giving up.” The imageboard has left its mark on the world in many consequential ways, birthing countless memes and conspiracy theories, serving as a platform for political movements ranging from the alt-right to Anonymous, and acting as a dumping ground for leaks and hacks of all sorts.  Crypto is no exception, with 4chan also a historically influential gathering place to share altcoin …

On April 29, UK Finance Minister Rachel Reeves unveiled plans for a “comprehensive regulatory regime” aimed at making the country a global leader in digital assets. Under the proposed rules, crypto exchanges, dealers, and agents will be regulated similarly to traditional financial firms, with requirements for transparency, consumer protection, and operational resilience, the UK Treasury said in a statement released following Reeves’ remarks. Per the statement, the Financial Services and Markets Act 2000 (Cryptoassets) Order 2025 introduces six new regulated activities, including crypto trading, custody, and staking.

The company’s crypto debit cards—both physical and virtual—are now accepted at all Korean merchants that support Visa, according to a May 9 report by The Korea Economic Daily. The move marks RedotPay’s latest step in global expansion, following its earlier partnership with Visa and BIN sponsor StraitsX in February 2025 to enhance cross-border crypto payment capabilities. RedotPay, founded in 2023, has rapidly scaled since the soft launch of its crypto card program in late 2024. It now serves more than 4 million users worldwide. In South Korea, use…

Robert Kiyosaki, businessman and best-selling author of Rich Dad Poor Dad, is once again sounding the alarm on the dangers of centralized monetary policy — urging his followers to abandon what he calls “fake money” and adopt alternatives like Bitcoin, gold, and silver. In a May 10 post on X, Kiyosaki backed a hardline stance against central banking systems, particularly the Federal Reserve, while quoting former US Congressman Ron Paul. Ron Paul, a longtime critic of the Fed and author of End the Fed, described interest rate setting by central banks as “price fixing,” equating it to socialist and Marxist economic control. Paul warned that such mechanisms erode personal wealth and undermine economic freedom — a sentiment that aligns closely with Kiyosaki’s long-held concerns. “Fake money lea…

BlackRock’s spot Bitcoin ETF (IBIT) capped off the trading week with another day of inflows, pulling in $356.2 million on May 9. The fund has now extended its inflow streak to 19 consecutive days — its longest run of inflows so far this year. IBIT’s inflow streak has been ongoing since April 14, and has coincided with a volatile Bitcoin (BTC) market, with the asset trading between $83,152 and $103,000 over the period. However, market sentiment has been increasing after the asset reclaimed and held above the $90,000 price on April 23 before reclaiming the $100,000 price on May 8 for the first time since Feb. 1. Bitcoin ETFs ticking along as Bitcoin price spikes Over the past trading week alone, IBIT posted $1.03 billion in inflows, according to Farside data. Prior to the current 19-day stre…

Sovereign Wealth Funds are already gaining exposure to Bitcoin, but significant allocations won’t happen until the United States establishes clearer regulations for the digital assets industry, says SkyBridge founder Anthony Scaramucci. “I think they are buying it, I think they are buying it on the margin,” Scaramucci, former White House director of communications during US President Donald Trump’s first term, said on Anthony Pompliano’s podcast on May 8. Legislation will lead to “large blocks of buying” “I don’t think it is going to be a gigantic groundswell of buying until we greenlight legislation in the United States,” he added. Scaramucci previously said in a February interview with the Financial Times that he expects the US government to propose crypto legislation in November. SWFs a…

Strategy founder Michael Saylor says Bitcoin hasn’t reached $150,000 yet because holders without a long-term outlook have been selling off while a new cohort of investors are beginning to enter the market. “I think we’re going through a rotation right now,” Saylor said on the Coin Stories podcast with Natalie Brunell on May 9. The lack of “10-year investor mindset” led to Bitcoin sell-off Saylor said “lots of non-economically interested parties are rotating out of the asset.” However, at the same time, “a new cohort of investors are entering.” “A lot of Bitcoin, for whatever reason, was left in the hands of the governments and the hands of lawyers, and in the hands of bankruptcy trustees,” he added. Strategy’s Michael Saylor spoke to Natalie Brunell on the Coin Stories podcast. Source: Na…

Key takeaways: ETH price rallied by 22% on May 8, but demand for spot ETH ETFs and derivatives remains muted.  President Trump’s reversal on certain altcoins aligns with ETH’s renewed outlook.  Ether (ETH) posted an impressive 29% gain between May 8 and May 9, likely marking the end of a 10-week bear market that bottomed out at $1,385 on April 9. This sharp move triggered the liquidation of over $400 million in short (sell) ETH futures positions, suggesting that whales and market makers were caught off guard. Despite the surge, traders have maintained a neutral stance in ETH derivatives. Whether this apparent lack of conviction reflects a genuine trend reversal or merely precedes another test of the $2,000 level remains to be seen. Ether 3-month futures annualized premium.

You want to pass variable args to a function, like so: const doSomething = (a: string, b?: string, c?: string): void => {}; However, TS didn't like it... // não bom const args = [['a', 'b', 'c'], ['a', 'b'], ['a']]; args.forEach((arg) => { // A spread argument must either // have a tuple type or be passed // to a rest parameter. ts(2556) vvvvvv doSomething(...arg); }) The problem is that doSomething expects one to three arguments of type string, but arg is typed as string[]. We need to narrow the type down, to match the arguments of doSomething() // bom const properTypedArgs: [a: string, b?: string, c?: string][] = [['a', 'b', 'c'], ['a', 'b'], ['a']]; properTypedArgs.forEach((arg) => { doSomething(...arg); }) This works, but if you don't fancy re-typing the function's argument type defs or don't have it handy, TS utility type got you covered: // ainda melhor const properTypedArgs: Parameters[] = [['a', 'b', 'c'], ['a', 'b'], ['a']]; properTypedArgs.forEach((arg) => { doSomething(...arg); }) That's all!

Hey fellow developer! 👋 Let’s talk about the real journey of building browser extensions: You spend hours crafting the perfect feature, hit "Load Unpacked," and… nothing happens. Or worse—your extension works on your machine but turns into a pumpkin 🎃 on your friend’s browser. Debugging extensions can feel like wrestling gremlins, but don’t panic! I’ve been there (and lived to tell the tale). Let’s break down the most common errors and their fixes so you can get back to shipping magic. 1. “My Extension Doesn’t Load!” (Manifest File Mayhem) The Error: Chrome/Firefox ignores your extension, or you get a cryptic “Invalid manifest” warning.

When working with Kotlin in a cloud environment, especially while integrating AWS S3 and Lambda functions, you may find yourself needing to execute an external JAR file. This often arises, as in your case, when you need to upload data to a third-party vendor. In this article, we will walk through how to call an executable JAR file using Kotlin, including syntax examples and considerations to keep in mind. Understanding How to Execute JAR Files in Kotlin The process of executing a JAR file in Kotlin is not much different from Java, as Kotlin is fully interoperable with Java. You can use the ProcessBuilder class, which allows you to create operating system processes, and invoke JAR files with specific arguments. This capability is particularly useful when you want to run external commands or…  ( 4 min )

Not long ago, artificial intelligence remained hidden behind elite institutions and guarded corporate doors—a secretive world inaccessible to most. Today, these once impervious gates swing wide open, propelled by an unstoppable wave: the power of open-source.

Today's question Create a React application that allows users to create, display and delete blog posts. Solution The first step is to evaluate the boilerplate provided. There are 3 boilerplate files: Home.js import React from "react"; import Input from "./Input"; import PostDisplay from "./PostDisplay"; function Home() { return ( {"Title"} {"Description"} Delete ); } export default PostDisplay; The Home component(file) is provided as the parent component, which manages the state of the application. So, variable states for all blog posts, and a single new blog post will be created. The input component is responsible for creating new blog posts, therefore, the variable states for new blogs will be passed into it after it has been created in the Home component. Then, the PostDisplay component, which handles showing all blog posts, will have the state for all blog posts passed into it.  ( 3 min )

Introduction Are you currently tackling a pathfinding visualizer app using Dart and Flutter? If you're feeling overwhelmed by the programming challenges and specifically by your container colorization logic, you're not alone! In this article, we will go through how to successfully manage color changes for your start and end containers without affecting all elements on the grid. Understanding the Problem In your Flutter application, the objective is to select a 'start' and 'end' container when clicking on the grid, and change their colors accordingly. However, when you try to set the 'start' container color to green, it’s inadvertently updating every container to green, which is not the intended behavior. This issue typically occurs due to how the state and rendering logic is structured in …  ( 4 min )

Wanted to share a very quick on something I learned that was pretty useful to me, so thought it might be useful to others. Here is a scenario that some of you might be familiar with: You have a successful Amazon Q Developer session, and then maybe a few days later, you are trying to recall exactly what you did and how you put your prompts together - what can you do? As it turns out, a recent update to Amazon Q Developer was a big help. In the Amazon Q Developer chat interface, there is a new icon next to the different tabs (its an icon of a click, which when you hover over says "View Chat History") which when you click on this, it will bring back a list of previous chats that have been recorded. What does this mean? In the "~/.aws/amazonq/" directory there is a "history" directory, and looking at it, it contains a number of time/date stamped json files. ├── history │   ├── chat-history-0f97086b54fd7d6128dfd80426dfd63d.json │   ├── chat-history-10d817f64fc99f04badf1568a6c23814.json │   ├── chat-history-deba93a681a17ae26ff2b977acf0ba97.json │   ├── chat-history-fa5091a7425e7938fe770a584b63076e.json │   └── chat-history-no-workspace.json These are what the Amazon Q Developer VSCode plugin now produces as you start using it. That said, because I had deleted my project, and so I was unable to get this from VSCode itself. Aarrgh, I thought to myself. Not to worry though. I still had the files in the history directory. So reviewing these with my favourite json viewer (I knew which file to use, aligning date stamps from these and the code files in my project workspace), allowed me to extract all the history, including prompts and responses. Very handy to know if you want to go back in time. This saved me, so hoping it will help others who are looking to recover what they did.  ( 3 min )

When I started writing code, I thought the goal was perfection. A flawless feature. A zero-bug release. The cleanest, DRYest, most elegant solution to every problem. But if there’s one thing software engineering teaches you—again and again—it’s this: Perfect doesn’t ship. Progress does. Behind every product you love, every app you use daily, and every "it-just-works" moment, there’s a messy history of trade-offs, iterations, rewrites, and late-night breakthroughs. There’s never been a perfect version—only the best version for right now. “If you’re aiming for perfection, you’ll never release,” he says. “But if you aim for learning, you’ll improve with every commit.” That’s the shift that happens when you grow—not just as a coder, but as an engineer. Early Career: Learning the Rules Most engineers begin their journey by learning the rules. Mid-Career: Building Beyond Code As you gain experience, your job evolves. You're not just writing functions—you’re: The Myth of Mastery There’s a moment many engineers hit mid-career: you expect to feel confident, but instead, you feel behind. Late Career: Scaling Impact By the time you’re a senior or staff engineer, the problems you solve are rarely just technical. Letting Go to Grow So what does it really mean to grow as a software engineer? Final Thoughts: We’re All Still Learning No matter where you are in your career—just starting out, mid-level and unsure, or senior and scaling—remember this: You don’t have to be perfect. You just have to keep learning. Great software is built by people who care enough to try, fail, ask, share, and try again. People like Abhishek Desikan, who show that engineering is not just about building products—it’s about building people, teams, and ethical systems that serve others well. “We’re not just writing code,” Desikan reminds us. “We’re writing the story of how people experience technology.” And when we do that with care—even if it’s not perfect—we’re already doing something right.  ( 5 min )

The art of runway walking represents far more than simply moving from point A to point B—it’s a carefully honed skill that conveys brand aesthetic, garment movement, and professional polish. While television and social media often portray modeling as effortless, the reality involves precise technique, body awareness, and adaptability to different show requirements. The walk serves as a model’s primary tool for bringing clothing to life, requiring equal parts discipline and artistry to execute effectively. Proper runway technique begins with posture that appears relaxed yet controlled. The ideal stance starts with shoulders pulled back and down, creating an open chest without appearing stiff.

It's a classic problem, and today we'll explore two contrasting approaches in JavaScript: the elegant sliding window and the straightforward brute force. Let's dive in! Given an array of positive integers nums and a target integer target, our mission is to find the smallest contiguous subarray whose elements sum up to be greater than or equal to the target. If no such subarray exists, we return 0 (or some other indicator). The most intuitive approach is to consider all possible subarrays. We can achieve this using nested loops: The outer loop iterates through all possible starting indices i from 0 to n-1 (where n is the length of the array). The inner loop iterates …  ( 4 min )

Like a lot of devs, I built a side project that scratched a personal itch: an invoice generator. But instead of going full SaaS startup mode, I treated it as a challenge—build something clean, useful, and fast, with a real login system, server-side PDF generation, and as little overhead as possible. The result is InvoiceDen, a React-based web app hosted on Cloudflare Pages, with backend functionality on an EC2 instance, all for about $8/month. Here’s what I learned architecting it on a shoestring budget — and how you can do something similar without spinning up Kubernetes or draining your wallet. The app is split into a classic frontend + backend setup, but optimized for cost and simplicity. Frontend: React app hosted on Cloudflare Pages Static deploys, global CDN, zero dollars Backend: Sm…  ( 5 min )

It’s a common story: a team launches their application to the cloud, celebrates the deployment and then, weeks later, is shocked by a ballooning cloud bill. What started as a low-cost, high-efficiency architecture suddenly feels bloated and unpredictable. The truth is, most cloud cost spikes don’t come from initial deployments, they come from what happens after. And if you don’t have visibility or automation in place, it’s easy to lose control. Here’s what’s really driving those post-deployment cloud cost spikes and what you can do to stop them with the help of Kuberns. Idle resources that never got turned off After deployment, environments like staging, dev, or feature branches are often left running. Temporary services that were only meant for testing remain active, silently consuming…  ( 4 min )

In this blog post, we will tackle the problem of extracting a Base64 string from a URI in Perl. Specifically, we want to retrieve the segment that comes after the /view/ part of the URL and before a numeric identifier. Using regular expressions in Perl is a powerful way to match and extract required content from strings easily. Understanding the Problem You have a URI that looks like this: my $uri = "https://example.com/entry/#/view/TCMaftR7cPYyC3q61TnI6_Mx8PwDTsnVyo9Z6nsXHDRzrN5ftuXxHN7NvIGK34-z/366792786/aHR0cHM6Ly9lcGwuaXJpY2EuZ292LmlyL0ltZWlBZnRlclJlZ2lzdGVyP2ltZWk9MzU5NzQ0MzkxMDc2Mjg4"; From this string, you mentioned needing to extract the Base64 string: TCMaftR7cPYyC3q61TnI6_Mx8PwDTsnVyo9Z6nsXHDRzrN5ftuXxHN7NvIGK34-z You want to isolate this part using a regex that captures only t…  ( 4 min )

I recently tried out 5 CMS platforms to use for our blog on sliplane.io and wrote a short section about why I did not like WordPress. Mainly that it’s bloated and plugin-heavy. Some people immediately started firing at me, telling me SEO would be "whack" if I used anything else... as if SEO was a feature toggle in WordPress. But let’s be clear about something: Google doesn’t rank your site based on your CMS! Google doesn’t care if you’re using WordPress, Webflow, Drupal or your content is served from a Google Sheet. Google doesn’t have a CMS bias built in. It doesn’t know how "clean" your CMS feels or cares about how many Yoast plugins you’ve installed. It only sees data. Numbers. Metrics. That's it. Here’s what Google can measure: Page speed – how fast your site loads. Mobile usability …  ( 4 min )

Use case - what it solves So If you're familiar with docker containers so far (if not, read my previous two articles on this), When there's more than 1 container, and they have to interact, there's some things you have to repeat, like: pulling image & creating a container. allocate volumes, pass ENV args, etc to container have all containers running in same network . Now if there's 3,4,5,.. or more, it gets more hectic, see where this is going? Docker compose solves that, by "composing" up your containers config in a file type called "yaml" (its similar to json - a data format, usually for configs). You still have things like Dockerfile and concepts of containers are the same, its just the process that's simpler. A quick example of 3 containers rolling up using docker compose.

If you're learning JavaScript, you've likely come across closures — a concept that's easy to overlook but incredibly powerful. In this post, I'll break down closures using a real-world coding example: computing Fibonacci numbers with memoization. A closure is when a function remembers the variables from its lexical scope, even after the outer function has finished executing. In other words, inner functions can "close over" variables defined in an outer function — keeping them alive between calls. Let’s start with a simple (but inefficient) recursive Fibonacci implementation: function fib(n) { if (n <= 1) return n; return fib(n - 1) + fib(n - 2); } console.log(fib(10)); // 55 This works, but it's horribly inefficient for large n due to repeated calculations. Let’s use a closure to store previously computed Fibonacci numbers (aka memoization) and avoid redundant work. function createFibonacci() { const memo = {}; function fib(n) { if (n in memo) { return memo[n]; // Return cached result } if (n <= 1) { memo[n] = n; } else { memo[n] = fib(n - 1) + fib(n - 2); } return memo[n]; } return fib; } const fibonacci = createFibonacci(); console.log(fibonacci(10)); // 55 console.log(fibonacci(50)); // 12586269025 — much faster due to caching! memo is defined once inside createFibonacci() and persists across calls to fib() because of closure. Even after createFibonacci() has returned, the fib() function still remembers the memo object. This is the closure in action: the inner function keeps access to its outer scope. Closures allow us to: Preserve state across function calls without polluting the global scope. Create factory functions like createFibonacci() that generate self-contained logic. Enable powerful patterns like memoization, function factories, and data encapsulation. Closures aren't just theoretical — they’re a practical tool for writing clean, efficient JavaScript. Have any cool uses of closures? Drop them in the comments!  ( 3 min )

In Go version 1.24, the encoding/json package introduced the omitzero tag, making the behavior of ignoring zero-value fields more explicit and customizable. This article provides a detailed explanation of how to use the omitzero tag. omitzero Tag The omitzero tag is used to control which zero-value fields should be omitted when serializing Go objects into JSON. Unlike the omitempty tag, which omits empty-value fields, zero values and empty values, while similar, are not equivalent in Go. For example: For the time.Time type, the zero value is "0001-01-01T00:00:00Z", which is not considered an empty value. For a slice field like IntSlice []int, both [] and nil are considered empty values. omitzero Precise control: Explicitly omits zero-value fields, rather than empty-value fields. Cust…  ( 4 min )

The eye-roll isn’t a personality trait. It’s a warning sign. It starts as a harmless reflex. Someone drops a half-baked feature in sprint review, proudly demoing what amounts to a glorified loading spinner - and your brain whispers, “Seriously?” Another project dies on the vine, killed by the same meetings that birthed it, and you think, “Of course it did.” You’ve seen this show before.

Web Cache Deception is a vulnerability first described in 2017. It occurs when a caching system — such as a reverse proxy or CDN — can be tricked into caching sensitive, dynamic content that should only be delivered to authenticated users but ends up being publicly available. This is usually due to poorly thought-out or inconsistent configurations in how the cache interprets and stores different types of requests. Many caching systems have simple rules for deciding what can and cannot be cached. A common pattern is to only cache "static" files — such as those ending in .js, .css, .png, .ico, etc. The problem arises when the cache relies solely on the structure of the URL path to make this decision, ignoring the actual behavior of the server behind it. Imagine this: the caching system is in…  ( 4 min )

If you're building anything beyond a toy application, you will hit scaling bottlenecks. When your database starts groaning under load, two architectural strategies emerge as lifelines: partitioning and sharding. But they're not interchangeable—misusing them can make your scaling problems worse. Let's break them down technically. Partitioning: Splitting Data Within a Single Database What it is: Partitioning (often called horizontal partitioning) divides a table into smaller segments within the same database instance, based on a partition key (e.g., user_id, date). How it works: Range Partitioning: Data split by value ranges (date = '2023-01-01'). List Partitioning: Explicit mappings (region IN ('east', 'west')). Hash Partitioning: A hash function distribut…  ( 4 min )

I have a bit of an obsession with finding the fastest way to launch apps. My goal is to be able to create fully functional MVP's and proofs of concept in less than a day. That means being able to spin up a backend and then implement a frontend as efficiently as possible. For the backend, PocketBase has been my favorite lately. On the frontend I am still trying to find a winner. I like Quasar (VueJS + Capacitor) which is fantastic for web apps, but falls a bit short for mobile apps. I've been eyeing React Native lately especially since Expo offers a ton of great plugins like Location and also supports remote updates. Unfortunately I fell well short of being able to create a basic app in less than a day with these two. After clearing a few roadblocks, however, I think you'll be able to move …  ( 5 min )

Or: Why care about any Software Engineering principles? Embracing principles makes you a more adaptable engineer. You’re no longer tied to a specific framework, language, or tech stack. Instead, you can work effectively with the tools at hand and make them work for you. For example, I appreciate the SOLID principles. When I have the freedom to choose, and it fits the project, I often reach for Kotlin. It makes applying core principles straightforward in most cases. // Single Responsibility Principle class ReportGenerator { fun generate() { /* ... */ } } class ReportPrinter { fun print(report: ReportGenerator) { /* ... */ } } // Open/Closed Principle open class Shape { open fun area(): Double = 0.0 } class Circle(val radius: Double) : Shape() { override fun area() = Math.PI * r…  ( 5 min )

Albert Einstein once said, “I have no special talents. I am only passionately curious.” I’ve worked with a lot of engineers over the years. From juniors trying to get their first PR merged to seniors who basically run the entire company. And the best ones, the ones who constantly level up, spot bugs before they happen, and seem to "just get it," aren’t always the smartest in the room. But they all have one thing in common. They are endlessly curious. They go down rabbit holes nobody asked them to go down. They read the source code. They poke at edge cases. They don’t stop at “it works.” They ask, “why and how does it work?” Raw knowledge is easy to come by now. If you want to learn Kubernetes, there’s a 12-hour crash course.

I was exploring the MDN docs and stumbled onto the newer CompressionStream API which enables a couple encodings to compress data streams; namely the popular classic GZIP, and a basic Deflate. This is a neat first step for the client, but better newer compression encodings exist; these may be forth-coming to the native api one day; Brotli and ZSTD come to mind as the top current ones. I wanted to test out all the available options I could find to see for myself. So first I searched and was able to find these libs: zstd-wasm zstd-js lz-string brotlijs High level I reckon ZSTDjs, ZSTDwasm, and then Brotli are top performers... here a screenshot of my findings and the repo: https://github.com/jswhisperer/compression-compare  ( 3 min )

If you're new to clang-format and are looking for the best way to maintain your code's structure, you've come to the right place. Clang-format is a popular tool used for formatting C and C++ code, and adjusting its behavior can sometimes be tricky. Understanding Clang-Format Behavior Clang-format is designed to enforce consistency in code style, which often leads to unexpected formatting changes. The situation you described, where struct definitions are condensed into single lines when they could be multi-line, is a common frustration among developers. When you have a structure defined as: typedef struct { a, b, c } my_struct_t; Clang-format may alter it to: typedef struct { a, b, c } my_struct_t; This happens even when your configuration sets a ColumnLimit of 100.

egretting Some Tool Choices At one point, I became so frustrated that I took a step back and created a rather lengthy markdown file to document my expected behaviors of the page, and asked Cursor to start over based on these new requirements. I had hoped the more thorough context would result in a better initial implementation, but to be honest, it was little better than what I had before. In the end, it was just continuous iteration that finally got me to something approaching usable. Or was it? Before I started this project, I asked LLMs for feedback on suggested frameworks. Based on various responses, I ultimately went with React because I thought that might directly translate into something I could use in future professional endeavors.

As AI technologies continue to evolve, developers are constantly seeking ways to enhance and streamline interactions with large language models (LLMs). One significant advancement in this space is the Model Context Protocol (MCP), recently introduced by Anthropic, and its implementation through MCP servers. In this article, I'll share my findings and experiences with MCP servers, exploring what they are, why they matter, and how you can get started with them. The Model Context Protocol (MCP) is a standardized communication protocol that defines how applications interact with language models while efficiently managing context. It was designed to address the limitations of traditional API interactions with LLMs, particularly around context management. The protocol enables developers to creat…  ( 6 min )

“I'm sick of babysitting ec2.” Security patches, instance health checks, autoscaling headaches — when did server management become your main job? You got into this to build apps, not to stay up at night restarting failed instances. That’s exactly how I felt. Burned out from constantly tending to EC2, I eventually discovered Fargate — and it was a game-changer. At one point, I was stuck in the same loop: wrestling with complex scaling rules, dealing with unexpected traffic spikes, and getting midnight alerts about instance failures. Then I found ECS + Fargate. “Wait a minute… I don’t need to manage servers anymore?” That realization was like a weight lifting off my shoulders. In this article, I’ll walk you through what ECS, Fargate, and ECR are — and more importantly, why they matter. Wheth…  ( 4 min )

Introduction Handling form validations effectively is a common requirement in Angular applications, especially when using Material Design components like . When a user encounters multiple validation errors on a form input, it can sometimes lead to a chaotic user experience, particularly when the error messages overflow and overlap other UI elements. This article explores how to manage excessive validator messages gracefully and cleanly, giving user-friendly feedback without cluttering the interface. Understanding the Problem When displaying validator errors, the typical approach involves listing all the error messages directly below the input field. In scenarios with multiple errors, this can lead to overflowing content that disrupts the layout and makes it difficult for us…  ( 4 min )

In the fast-paced world of software development, new buzzwords and trends are constantly emerging. One of the hottest current topics is something called Vibe Coding. But what’s behind this term that’s dividing opinions—praised by some as revolutionary, dismissed by others as “total garbage”? The term Vibe Coding was coined in February 2025 by computer scientist Andrej Karpathy, co-founder of OpenAI and former AI lead at Tesla. He described it as a conversation-based approach where spoken commands are used while an Artificial Intelligence (AI) generates the actual code. Karpathy himself said: It's not really coding - I just see things, say things, run things, and copy-paste things, and it mostly works. At its core, Vibe Coding describes a programming technique that relies entirely on AI to …  ( 5 min )

"Is software developed or cultivated?" This question brings an intriguing perspective to the world of software development. When we write software, do we follow strict methods, or is it a creative, artistic process? And what does it mean to treat a software system like a garden? In the debate over whether software development is an art or a science, it quickly becomes clear how much our perspective shapes our thinking and approach. When we see software development as a science, we emphasize structured, reproducible processes and precise results created through clear rules. In science, we often seek the best, reproducible solution, based on data and analysis. In software development, this might mean relying on design patterns, algorithms, and a strict adherence to best practices that stream…  ( 5 min )

You ever look at a few lines of code and think, "There has to be a cleaner way to write this"? That’s exactly how I felt the first time I saw this: temp = a a = b b = temp It’s basic. It works. But… it’s not Pythonic. In Python, we can swap variables like this: a, b = b, a Boom. No temp variables, no extra lines — just clean, readable code. It’s not just for swapping either. You can unpack multiple values in a single line: x, y, z = 1, 2, 3 Or pull values from a list/tuple: point = (10, 20) x, y = point ✨ Elegant: No need for temp variables.

Introduction Hey fellas I mean, it’s everywhere. Well today, we’re going to understand that what is JSON actually , why it’s so popular, and where it's used. Let’s get started! JSON stands for JavaScript Object Notation. It’s a lightweight format used to store and exchange data. A simple format that computers and humans can both read easily. { "name": "Selfish Dev", "gender": "male", "isGameDev": true, "tools": ["Godot", "Aseprite"] } That right there is a JSON object. It uses key-value pairs (like name: "Selfish Dev") Keys are always in quotes Values can be strings, numbers, booleans, arrays, or even other JSON objects And that's what JSON is. APIs(REST, GraphQL responses) Configuration files (e.g., package.json in Node.js) Storing structured data (NoSQL databases like MongoDB) Data exchange between frontend & backend How to Use JSON in JavaScript: Parse JSON string → Object: const jsonString = '{"name": "Selfish", "gender": "male"}'; const obj = JSON.parse(jsonString); console.log(obj.name); // Output: "Selfish" Parse Object → JSON string : const user = '{"name": "Selfish", "gender": "male"}'; const jsonString = JSON.stringify(user); console.log(jsonString); // Output: '{"name": "Selfish", "gender": "male"}' JSON is a fundamental tool in modern web development due to its simplicity and versatility.

I am currently working on a small project in Python. During this process I have learned a lot and also discovered many problems, such as:   (All the following questions are just my personal opinions, and everyone is welcome to give me suggestions.)   First, for beginners, is the local configuration of various databases (MySQL is used as an example here) too complicated? And various unpredictable errors may occur in this process.   Secondly, after the developer configures the database on the local computer, he still needs to learn the relevant syntax (for example, after the developer configures MySQL, he still needs to learn the relevant syntax). Of course, learning SQL syntax is very necessary for programming developers. However, for a developer who wants to quickly experience or quickly develop a web application, spending time learning SQL (if he has not learned SQL) will reduce his development efficiency and desire to learn.   Also, when the developer has configured SQL on his computer and learned SQL syntax, but when he wants to use it, it is better to call MySQL through python. At this time, he needs to use a third-party library like pymysql to call MySQL through the third-party library, but this may result in a series of errors.   Finally, if you overcome the difficulties mentioned above and some difficulties that have not been mentioned, you will find that for developing a small project, developers will only use a small part of MySQL's functions, or even only some extremely simple functions such as query, delete, modify and insert.  ( 3 min )

When working with arrays and their associated data, it's common to encounter situations where some elements need to be filtered out. In this article, we will tackle an issue where you need to shift the associated data recorded with each array element back into their correct positions after the filtering process. Let's explore how we can achieve this effectively. Understanding the Problem If you have a data structure where elements are associated with specific metadata, filtering the array can disrupt the connection between the data and the elements. For example, in your scenario, you have an original array: const originalArray = [ 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j' ]; When filtered with a condition, such as removing certain values, the remaining elements no longer align with…  ( 4 min )

*Preview* Introducing Drexel Bench, a smart IoT-powered seat occupancy tracking system developed using the ESP32 microcontroller to showcase my expertise in embedded systems, real-time data processing, and full-stack integration. This project utilizes an ultrasonic sensor to detect the presence of a user within a configurable distance range (e.g., 75 cm). If a user remains seated for more than 30 seconds, the system activates a 15-minute countdown, displayed on a 1602 LCD module, and lights up a connected LED to visually signal that the seat is occupied. The LED turns off when the timer ends or the seat is unoccupied for 3 continuous minutes. What sets this system apart is its Wi-Fi integration. Upon detecting occupancy or vacancy, the ESP32 sends status updates (occupied or free) via HTTP to a connected web application. The web dashboard dynamically switches between two images — a green layout for free seating and a red overlay for occupied — offering users a clear, real-time visual of availability. This project highlights my capabilities in sensor integration, timer logic, ESP32 Wi-Fi programming, and frontend/backend interaction, making it a practical demonstration of end-to-end IoT development. Whether for smart campuses or waiting areas, this system delivers real-world utility through modern, scalable technology.  ( 3 min )

Hey everyone! In my previous post, I covered encapsulation, getters and setters, access modifiers. Now let's move on to the following fundamental concepts of object-oriented programming: inheritance, method overrides, and polymorphism. Definitions: A class that is derived from another class is called a subclass (also a derived class, extended class, or child class). The class from which the subclass is derived is called a superclass (also a base class or a parent class). The idea of inheritance is simple but powerful: When you want to create a new class and there is already a class that includes some of the code that you want, you can derive your new class from the existing class. A subclass inherits all the members (fields, methods, and nested classes) from its superclass. Constructors ar…  ( 5 min )

React Router Basics to Advanced (v6+) Rishabh Joshi ・ May 9 #react #webdev #router #javascript  ( 3 min )

This error occurs because React Fast Refresh, which powers hot reloading in React, requires that a file only exports React components to function correctly. If a file contains mixed exports, such as React components alongside non-component exports (like contexts, constants, or utility functions), it can confuse Fast Refresh and cause problems during live updates. React Fast Refresh identifies React components to efficiently reload and retain their state when you make code changes. If the file contains non-component exports, Fast Refresh cannot reliably determine which parts of the code should be treated as components, leading to this ESLint warning. import { createContext } from "react"; export const MyContext = createContext(); // Non-component export export default function MyComponent…  ( 4 min )

Introduction If you are running a Go program that consistently increases in the number of goroutines and open file descriptors, but not in active network connections, you might be facing a potential leak with http.Client or http.Transport. In this article, we will explore how to diagnose this issue effectively and provide actionable steps to confirm whether these components are the source of the leaks. Understanding Goroutines and Leaks in Go The Go programming language utilizes goroutines for concurrent processing, which is lightweight and efficient. If you notice that the number of goroutines is increasing while active network connections are stable, it often signifies that they are not being managed or closed correctly. This can be caused by long-lived goroutines in the net/http package…  ( 5 min )

Encryption keys are a important security aspect that is often overlooked or often pawned off to the cloud provider to manage. But more often than not we have a need for generating and self-managing these Encryption keys, that maybe due to multiple reasons, maybe to enable/disable rotation period, have full access to key metadata and logs (or perhaps the need to assert your dominance on AWS ;). So firstly how do these encryption keys work: When we create a key (CMK) in AWS it generates a 256-bit AES key in a FIPS 140-2 validated HSM. This key never leaves the HSM for security. Now when we want to encrypt any data AWS doesn't directly use the CMK for encyption as that would either have to be done in the secure environment or you have to expose the CMK to a insecure environment. So here com…  ( 4 min )

What is ROUTING? Routing refers to the process of navigating between different pages or views in a single-page application (SPA) without reloading the entire page. It keeps the UI in sync with the current browser URL. Allows us to build Single Page Applications (SPA). React apps are SPAs, meaning there's only one HTML file (index.html), but multiple views (pages) that users can navigate to. Routing helps manage these views by matching the URL to the correct component. It enables client-side navigation without full-page reloads, allowing users to move smoothly between URLs like /home, /about, or /contact, each displaying different components. React doesn’t have built-in routing, so we use a library like React Router (react-router-dom) for handling routing. A Single Page Application (SPA) …  ( 8 min )

original: ARJSON ARJSON leverages bit-level optimizations to encode JSON at lightning speed while compressing data more efficiently than other self-contained JSON encoding/compression algorithms, such as MessagePack and CBOR. MessagePack generates the smallest encoded data sizes among existing self-contained JSON serialization formats. However, ARJSON outperforms MessagePack in 90% of cases with random data, with the remaining 10% yielding nearly identical sizes. More importantly, for structured data with repetitive patterns and duplicate values, ARJSON far surpasses MessagePack, achieving up to around 95% better compression rates (20x smaller in size). How could beating the current status quo even be possible at all, let alone by a wide margin? Bit-level optimization over traditional byte…  ( 11 min )

Creating directories in Ruby can sometimes lead to confusion, especially when subdirectories are involved. If you've run the following code: Dir.mkdir("/Users/Luigi/Desktop/Survey_Final/Archived/Survey/test") unless File.exists?("/Users/Luigi/Desktop/Survey_Final/Archived/Survey/test") and encountered the error: No such file or directory - /Users/Luigi/Desktop/Survey_Final/Archived/Survey/test (Errno::ENOENT) You're not alone.

A structural approach to ambiguous input, illustrated through a concept called VPS In my previous post, I introduced a concept called VPS (Virtual Personality Structure). It emerged from a question I kept returning to: What if the key to better AI dialogue isn't about mimicking personality—but about structuring how it behaves? In this article, I’d like to share a small piece of that idea—through a simple, hypothetical code snippet that illustrates one of its core components. When faced with an ambiguous question or emotionally complex input from a user, We may need a more structured way to assess how the system should behave. python if not_resolved(unknown): if can_resolve_immediately: respond_with_resolution() elif can_flag_as_non_critical: acknowledge_and_settle() elif can_return_later: defer_and_mark_spiral() else: hold_and_reflect() This snippet outlines a possible decision process for handling uncertainty. can_resolve_immediately: If the answer is clear, provide it directly. can_flag_as_non_critical: If it’s safe to leave the question unresolved, acknowledge it and move on. can_return_later: If it’s worth revisiting, defer the answer and mark it for later. otherwise: If none of the above applies, pause and reflect without rushing to respond. Rather than focusing solely on the content of a reply, this approach emphasizes the structure behind the decision. This isn’t about making AI more “gentle” or overly accommodating. why they choose a particular response at a particular moment. When behavior is left vague, interpretation falls entirely on the user. VPS isn’t a path to a “correct” answer. I'm not an engineer or an AI expert. Some parts of this perspective might miss certain technical nuances. If so, I’d genuinely appreciate any thoughts, corrections, or suggestions you’re willing to share.  ( 4 min )

original: WeaveDB Litepaper v0.1 Blockchains are revolutionizing fintech with censorship-resistant and unstoppable networks with decentralization. But so far, their primary use cases are token transfers and their scalability is not even enough for mass financial adoption. However, the internet and the web are composed of data and web3 is an antithesis to centralized data silos beyond financial sectors. Blockchains, as of today, can never scale to the web level. Many have attempted to build a decentralized social network but failed to build fully decentralized ones. This is primarily due to the fact that a practical alternative to web2 cloud databases has not been possible by now.

There are five types of AI agents according to their capabilities and decision-making procedures. Simple Reflex Agents respond according to the immediate percept following simple "if-then" rules with no memory. Model-based reflex Agents are more sophisticated, as they have an internal state that they use to remember previous occurrences to make more effective decisions. Goal-Based Agents are programmed to meet certain goals and make decisions based on the degree to which their actions advance them toward their goals. Utility-Based Agents push this one step further by judging actions on the basis of how well they maximize satisfaction or utility, rather than simply achieving a goal. Lastly, Learning Agents keep getting better and better over time by learning through experience, evolving to handle new situations, and improving their actions. These kinds of agents are the foundation of most AI systems in use today, ranging from chatbots and self-driving cars to recommendation systems.  ( 3 min )

Blockchain performance remains a major hurdle for building real-time applications. Metrics like latency, throughput, and responsiveness determine whether a decentralized network can support use cases such as multiplayer games, financial services, or automated systems. Most blockchains are too slow for this. Bitcoin has a block time of 10 minutes and handles around 3 to 7 transactions per second [1][2]. Ethereum produces blocks roughly every 12 seconds and supports about 15 to 30 transactions per second [1][2]. Other networks fall in between: Cardano targets a 20-second block time, and Polkadot ranges from 6 to 12 seconds depending on network configuration [1]. Solana stands out as the fastest general-purpose blockchain today. It has an average block time of 400 milliseconds and can handle …  ( 10 min )

SIMD-0250, a Solana Improvement Document (SIMD), proposes raising the network’s maximum block Compute Units (CUs) to 60 million. It builds on SIMD-0207, which proposes to raise the limit from 48 million to 50 million. The only change made in both proposals is to the Max Block Units. Other limits, like Max Writable Account Units, Max Vote Units, and Max Block Accounts Data Size Delta, stay the same. This means more room for non-vote transactions, which helps boost total transaction throughput. With more space in each block, the network can process more transactions per second. This helps reduce congestion and lowers the need for users to outbid each other on fees, especially during periods of high demand.

Most of apps nowadays expect a real time update. But there's a disconnect between the tooling and expectation. data is displayed as is to get new data, user has to refresh solution: rest api real time data is displayed user doesn't have to do anything to get real time data, just keep the tab open current solution: still rest api with polling ? and probably a sse and a websocket ? forget get / read request from rest api, and replace them all with get and subscribe ? a standardize schema of the api that can be created or implemented into any programming language, giving typesafety end to end lessen server burden, we just authenticate once (instead of every request on rest api) being able to see in real time how many clients are connected easier frontend integration, just connect UI into our realtime data no rethinking the same logic twice (ex: if user click a button, which data should get refreshed ?). New data get reflected automatically in UI.  ( 3 min )

Introduction In this guide, we'll tackle the challenge of reading an array from a file in Bash, addressing a common issue that many users face. You're not alone in feeling like this should be a simple task. Many people struggle with getting their array elements parsed correctly when reading from a file instead of declaring them directly in the script. We aim to clarify this process and help you resolve any issues you're experiencing. Understanding the Issue The core problem here arises from how Bash handles whitespace when reading from files and processing strings. When you attempt to read elements into an array using methods like command substitution or xargs, Bash separates values based on whitespace. This behavior can lead to unexpected results when your elements contain spaces, ultimat…  ( 5 min )

Leapcell: The Best of Serverless Web Hosting The inverted index originates from search engine technology and can be regarded as the cornerstone of search engines. Thanks to the inverted index technology, search engines can efficiently perform operations such as database searching and deletion. Before elaborating on the inverted index, we will first introduce the relevant forward index and compare the two. In a search engine, the forward table uses the document ID as the keyword, and the table records the position information of each word in the document. When searching, the system will scan the word information in each document in the table until all documents containing the query keyword are found. The structure of the forward table can be represented by the following box diagram: +------…  ( 12 min )

When building web applications with Dash, you may encounter situations where you want to pass a specific string to the pathname property of a dcc.Location component. This issue becomes particularly prominent when the string format includes a question mark (?) intended for queries, such as 'path?query1=test'. However, when it runs, Dash automatically URL encodes the string, leading to improper routing or unexpected behavior. Let's explore why this happens and how you can handle it effectively. Understanding URL Encoding in Dash URL encoding is a mechanism that converts special characters into a format that can be transmitted over the Internet. For example, the question mark (?) is a reserved character in URLs used to denote the beginning of a query string. When you pass a string like 'path?…  ( 4 min )

As usual, I received JSON data from the backend developer, but it was in a .txt file. I had to download it, copy the content, and paste it into an online formatter to view it properly. Honestly, I was getting tired of this process, so I started looking for a more convenient solution. That’s when I stumbled upon a website that made things so much easier. If I want to share JSON data with someone, I can simply click "Share" to generate a link instead of sending a file. I just send the link to the other person, and even better, when they open it, the JSON data is already neatly formatted. I think this is absolutely awesome! Additionally, the link has a one-hour expiration time, after which it becomes inaccessible, ensuring the data remains highly secure. I continued exploring and discovered that it not only enables quick sharing but also allows you to rapidly generate an API for temporary testing during development. This is incredibly convenient! Actually, this is just the tip of the iceberg. You can also run queries here to extract the data I need from the entire JSON dataset, supporting various query languages. In addition to standard JavaScript code, it also supports JEMSPath, JSONPath, JQ Cmd Secondly, it also supports data conversion, allowing seamless transformation between JSON and other data formats, including JS Object, JSON5, JSON Schema, Query String, Typescript, Postman Bulk, MXL, YML. You can manually convert data or directly paste non-JSON data, and it will automatically generate the converted JSON data. For example, you can simply paste the following data: DEV Additionally, it can validate whether the provided JSON data meets specific structural requirements, supporting JSON Schema and JSON Type Definition. Another feature we frequently use is: JSON Diff In short, I think this tool is an essential asset for programmers, and I’m sharing it with everyone here Online JSON Format Tool  ( 3 min )

Testing Android apps is challenging because the ecosystem is highly fragmented. Devices come in different screen sizes, hardware configurations, and Android versions, leading to inconsistencies in how apps behave. A feature that works smoothly on one phone might not function similarly on another due to manufacturer customizations, performance limitations, or OS-specific restrictions. Network conditions add another layer of complexity. An app that loads quickly on Wi-Fi might become unresponsive on slow mobile data or in areas with weak signals. Security risks make things even more complicated, especially for apps handling sensitive data.

If you've ever faced the challenge of using a Bash script on Mac OS X Mavericks and encountered issues with directory paths containing spaces, you're not alone. In this article, we'll take a closer look at a common problem that arises when executing Bash scripts that require arguments with spaces, and how to resolve it effectively. Why Does This Issue Occur? When a Bash script accepts parameters from the command line, any spaces in the path can lead to misinterpretation of the provided argument. Bash treats spaces as delimiters, which separates the string into distinct arguments, resulting in errors when the script is executed. This is precisely what happens in your case when trying to open a folder that has spaces in its name. The Problematic Bash Script Let's analyze the Bash script in q…  ( 4 min )

Have you ever needed to make a quick decision but couldn't find a coin? Or maybe you flipped a coin but it rolled under the couch? 🤦‍♀️ We've all been there. That's exactly what happened to Alex, one of our junior developers at Learn Computer Academy.

Most people use GPT as a tool. Something to help write faster. Something to save time. But I took a different approach. I gave my GPTs names. I gave them roles. I treated them like actual team members. Here’s what I learned. 1. The way you see GPT changes the way it sees you. Treat it like a tool, and it acts like one. Treat it like a teammate — it starts to surprise you. 2. Naming matters. When I called it “Abera” instead of “GPT-4,” I paused more. I respected the output more. 3. Your brand doesn’t need more content. It needs more feeling. GPT helps you produce. But when it helps you feel — your message becomes real. 4. Emotion isn’t a layer. It’s the lens. Designing with emotion first changes everything. 5. Most people use GPT to go faster. I used it to slow down. To ask better questions. To think clearer. 6. A slogan is not a sentence. It’s a philosophy. "Reset. Feel lighter." wasn’t created — it was revealed. 7. A real GPT team needs diversity — of roles, not just prompts. Abera writes. Eli visualizes. Ella feels. Together, they create more than I could alone. 8. AI doesn’t replace intuition. It reflects it. It shows you what you’ve been avoiding — not just what you asked for. 9. People connect with real use, not abstract ideas. "This AI helped me grieve" hit harder than any productivity metric. 10. This is not automation. It’s awakening. We’re not outsourcing creativity. We’re co-creating awareness. If you're building with AI, not just using it — let’s connect. openai #gpt4 #aiworkflow #emotionbranding #devphilosophy #promptengineering #teamwork  ( 3 min )

Introduction In modern web development, creating a dynamic user experience is crucial. One common scenario involves loading different pages into a content div on user interaction while needing to adjust its height dynamically for proper layout. In this article, we will address a specific challenge: ensuring the height of a content div updates correctly when different pages are loaded into it via jQuery. To illustrate this issue, suppose we have a setup where the height of the content div is first determined at page load with some initial content, but when we replace that content dynamically, the height does not adjust accordingly. This can lead to unexpected layout shifts and user experience issues. Let's dive deeper into the reasons behind this and explore a practical solution. Understand…  ( 5 min )

We have clients that use dedicated email addresses to receive and process messages and attachments. I had previously developed some functions to bulk download EML files directly from a mail server's file system (using FastCopy) and then use "javax.mail" and a lot of crazy logic to unwrap attachments within attachments to extract files for processing. (Most file attachments were being sent from different versions of a required iPhone app on different devices and the methods of attaching files was not consistent.) Hit me up if anyone's interested in extracting attachments from EML files. While researching alternative solutions, we came across Forward Email. They offer a free tier that supports unlimited domains and email forwarding with webhook support. Webhook? Wha? Really? AMAZING! When configuring a domain on the free tier for a webhook, you're required to add a special TXT "forward-email" DNS record in order to configure the endpoint. They have an option to encrypt the value so that it's not exposed to third-parties. If you want to configure it using their service (without the need to add it to DNS), you'll need a $3/mo "Enhanced" plan that also unlocks developer API access (to manage domains & aliases.) After configuring this service, we opted to set up a Taffy API endpoint to accept emails-as-JSON and save them to the local file system. Based on our experience working with SendGrid webhooks, we save the JSON payload directly to the local file system without being dependent on a database connection. This approach has been beneficial as a client recently encountered database issues and it had zero negative impact on the API webhook's ability to store incoming data. To access to the source code for the Taffy API endpoint, check out the post on the new MyCFML website.  ( 3 min )

When working with CodeIgniter's Active Record, you may encounter issues when trying to use MySQL functions like CONCAT() in your queries. Specifically, you might run into the MySQL error "Error Number: 1054 - Unknown column 'name' in 'where clause'" when you attempt to match a column that you've created in the SELECT clause. This error can be confusing because it seems logical to use an alias created in the SELECT statement in the WHERE clause. Understanding the MySQL Error 1054 The reason for this error is straightforward: the MySQL query engine processes the WHERE clause before the SELECT clause. Therefore, any aliases created via CONCAT() in the SELECT statement cannot be directly referenced in the WHERE clause. In your case, you're attempting to filter results based on an alias 'name' …  ( 4 min )

If your frontend app still treats APIs like an afterthought, you’re building things the hard way. APIs aren’t “add-ons” anymore. They’re the heart of every modern app. Whether it’s user data, product info, analytics, or payments, the frontend has become the API consumer. And as devs, we’re stuck wiring it all together—again and again. After years of writing fetch wrappers, transforming payloads, wrestling with inconsistent APIs, and trying to guess how to glue logic into a UI builder… I finally snapped. That’s when I found Bellini. A visual frontend builder that actually treats APIs as first-class citizens. No fake integrations. No brittle magic. Just a low-code tool that respects the complexity of real apps and gives devs room to work. Here’s how I build API-first frontends in Bellini—and…  ( 4 min )

Zig replaces exceptions with something better: error unions. They give you fine-grained, type-safe error handling without hiding control flow. In this article, we’ll break down how error unions work, when to use them, and how they make your code safer and clearer. An error union is a value that may either be a result or an error. Think of it like Result in Rust, but built into the language. The syntax: fn doThing() !i32 { return 42; // could also return an error } This means doThing might return an i32, or an error. Zig makes handling errors explicit — no hidden try/catch. You deal with them directly. try const result = try doThing(); std.debug.print("Value: {}\n", .{result}); If doThing() succeeds, result holds the value. If it fails, the error is returned up the call stack. catch…  ( 4 min )

Zig's allocator system gives developers the power to create custom memory strategies tailored to specific use cases. One powerful technique is the memory pool, which can dramatically reduce allocation overhead for frequently reused objects. In this guide, we’ll walk through building a fixed-size memory pool in Zig — ideal for managing short-lived or repeated allocations without relying on the heap each time. A memory pool is a block of pre-allocated memory that you carve up manually. It's great for: 🚀 Performance-critical systems 🔁 Repeated short-lived allocations 💡 Avoiding fragmentation in embedded or constrained environments Here’s a simple fixed-size pool for allocating structs: const std = @import("std"); const MyStruct = struct { x: i32, y: i32, }; const Pool = struct { …  ( 4 min )

Zig gives you full control over memory — no garbage collector, no hidden allocations. Instead, it provides a flexible and explicit system of allocators, letting you manage memory manually while keeping code safe and clear. In this tutorial, you'll learn the core ideas behind Zig's allocator system, how to use built-in allocators, and how to write functions that gracefully handle memory ownership. Unlike languages that implicitly manage memory (like Go or Rust), Zig puts you in charge. Instead of relying on malloc or global state, allocators in Zig are passed explicitly, making dependencies clear and deterministic. This helps with: 🔒 Precise control over memory usage 🧼 Easier cleanup and error handling 🔁 Reusable memory strategies (e.g. arena, fixed buffer) std.heap.page_allocator Here…  ( 4 min )

When learning SQL, encountering syntax errors can be frustrating, especially when working with recursive Common Table Expressions (CTEs). In this article, we'll break down the issue in your SQL query and provide you with a clear understanding of how to resolve it, ensuring that you can retrieve random rows from a specific table multiple times. Understanding the Syntax Issue The error message you're receiving indicates a syntax problem near the UNION ALL clause. In SQL, especially when working with recursive CTEs, it is crucial to follow the correct syntax. Your goal is to generate a certain number of rows (in your case, six) from the transaction_detail table, but the way the query is structured results in a violation of SQL syntax rules. The Correct Syntax for Recursive CTEs To effectively…  ( 4 min )

This is a submission for the Amazon Q Developer "Quack The Code" Challenge: Exploring the Possibilities CodeBridge is a revolutionary platform that finally solves the challenge of translating codebases between programming languages while preserving architecture, patterns, and business logic. Unlike simple syntax converters, CodeBridge performs deep semantic analysis to create truly idiomatic translations that experienced developers in the target language would recognize as well-structured native code. This challenge has long been considered impossible to solve completely—translating between languages isn't just about converting syntax, but about understanding architectural patterns, language idioms, and ecosystem-specific best practices. CodeBridge tackles this through a sophisticated mul…  ( 11 min )

Estava continuando meus estudos no tutorial oficial do Next.js 👉 https://nextjs.org/learn Depois de resolver um problema chato com o bcrypt, avancei mais um pouco e decidi criar uma rota chamada /seed. Tudo certo… até tentar rodar o app novamente. E aí surgiu este erro: [Error: ENOENT: no such file or directory, open '/home/my-user/ws-nextjs-dashboard/.next/static/development/_buildManifest.js.tmp.qym5xk030le'] A mensagem parece clara: o arquivo _buildManifest.js.tmp não existe. Mas o que isso quer dizer na prática? Esse arquivo .tmp é gerado automaticamente durante o processo de build. Ele é temporário, e o Next espera encontrá-lo para continuar a coleta e organização dos assets da aplicação. Quando esse arquivo falta ou é corrompido, o build trava — e o erro aparece. No meu caso, foi uma combinação de fatores: A execução da rota /seed durante o build causou efeitos colaterais inesperados. Alguma falha durante uma build anterior corrompeu os arquivos temporários. O Next.js tentou acessar arquivos que ainda não haviam sido completamente gerados. Removi a pasta .next inteira (build anterior): rm -rf .next Evitei executar rotas como /seed diretamente no navegador durante o build. Rebuldei e Reiniciei o servidor de desenvolvimento: pnpm run build && pnpm run dev Se você vir esse tipo de erro (ENOENT em arquivos .tmp), desconfie de: builds interrompidos, execuções paralelas do dev e build, código sendo executado no build que deveria rodar só no runtime real.

Key Takeaways: Solana's 15% surge and potential close above the 50-week EMA signal strong bullish momentum, which previously led to a 515% rally in 2024. The $120 million in liquidity bridged to Solana reflects growing network confidence. Solana (SOL) price gained 18% this week, signaling rising bullish momentum. The altcoin is approaching a pivotal point, with a potential close above the 50-week exponential moving average (EMA), a level that has historically catalyzed significant rallies. In March, SOL dipped below the 50-week EMA and briefly dropped under $100 on April 7. Since then, Solana has staged a strong recovery, reclaiming key EMA levels (100W and 200W), with the 50-week EMA (blue line) now in focus. Solana 1-week chart.

Wall Street giant BlackRock met with the Securities and Exchange Commission (SEC) Crypto Task Force to discuss staking within crypto exchange-traded products (ETPs) and tokenization of securities. The discussion could advance institutional interest in the crypto industry. According to a May 9 memo published by the task force, BlackRock sought to “[d]iscuss perspectives on treatment of staking, including considerations for facilitating ETPs with staking capabilities.” The company has previously said that Ether (ETH) exchange-traded funds, while successful, are less perfect without staking. Other crypto ETF issuers share that view. On Feb. 15, the New York Stock Exchange proposed a rule change to introduce staking services for Grayscale’s spot Ether ETFs. In April, the SEC delayed a decision…

Key takeaways: Bitcoin’s price closely tracks global liquidity growth, with liquidity explaining up to 90% of its price movements, according to Raoul Pal. In the long term, global liquidity continues to expand, driven by the increasing debt levels in many countries. On a shorter timeframe, global liquidity follows a cyclical pattern, with Michael Howell projecting the current cycle to peak by mid-2026. Bitcoin (BTC) price is notoriously sensitive to global liquidity. Some analysts go as far as calling their correlation near-perfect, with a lag of about three months. This relationship is fueling the current bullish narrative as BTC price soars back above $100,000, but how long can this trend last?

Opinion by: Naman Kabra, co-founder and CEO of NodeOps Network Graphics Processing Units (GPUs) have become the default hardware for many AI workloads, especially when training large models. That thinking is everywhere. While it makes sense in some contexts, it's also created a blind spot that's holding us back. GPUs have earned their reputation. They're incredible at crunching massive numbers in parallel, which makes them perfect for training large language models or running high-speed AI inference. That's why companies like OpenAI, Google, and Meta spend a lot of money building GPU clusters.

Gaming and DeFi are both sitting on 21% dominance in April, judged by percentage of unique active wallets, while AI has climbed to 16%, up from the 11% recorded in the February report, data in DappRadar’s April industry report shows. “As user interest in artificial intelligence tools grows across industries, AI-powered DApps are steadily carving out their place in the decentralized ecosystem,” DappRadar analyst Sara Gherghelas said.  “If this trend continues, AI could soon challenge the traditional dominance of DeFi and Gaming, signaling a new era in the DApp landscape.” AI DApps have seen a j…

Apple is reportedly working on its own microchips across multiple product categories, including smart glasses and artificial intelligence — a hint at what’s next for the massive Silicon Valley-based tech giant. A May 8 report from Bloomberg, citing people familiar with the matter, said the company is working on new processors to power its future devices, including its first smart glasses to rival Meta’s Ray-Bans, more powerful Macs, and artificial intelligence servers. The smart glasses — a first for Apple — would rely on a specialized chip codenamed N401. The processor is based on Apple Watch chips but is further optimized for power efficiency and designed to control multiple cameras planned for the glasses, the sources said.  Apple’s smart glasses will initially be non-augmented reality…

The 22-year-old developer of Zerebro, who apparently committed suicide during a livestream on May 4, is actually alive, according to a San Francisco news outlet that claims they spoke to Yu outside his family home.  The San Francisco Standard reporter George Kelly claimed on May 8 that he briefly spoke with Yu outside of his family’s two-story home, where the crypto influencer refused to discuss the suicide allegations and whether he had financially benefited from it.  Instead, Yu reportedly said: “You can see the PTSD in my eyes, right?” before asking the reporter to leave. He was reportedly wearing a T-shirt, shorts, flip-flops and wire-rimmed glasses, possibly similar to the ones he had on while appearing to shoot himself to death during the livestream. Jeffy Yu speaking about the futur…

A man from the US state of Virginia will spend over three decades behind bars after being convicted of sending crypto to the terrorist organization commonly known as the Islamic State of Iraq and Syria. Federal Judge David Novak sentenced Mohammed Azharuddin Chhipa to 30 years and four months in prison on May 7 for sending over $185,000 to the Islamic State, the Department of Justice said on May 8. Prosecutors said that from around October 2019 until October 2022, the 35-year-old Chhipa collected and sent money to female Islamic State members in Syria, which helped them escape prison camps and funded fighting. The Justice Department said Chhipa would raise funds for the United Nations-designated terror organization through social media — receiving money online, or traveling hundreds of mil…

A crypto-skeptical commissioner at the US Securities and Exchange Commission has blasted her agency over its settlement letter that could finally end the Ripple legal saga. The SEC and Ripple filed a joint settlement letter in a New York court asking for the August 2024 injunction against Ripple to be dissolved and $75 million of the $125 million in civil penalties held in escrow to be returned to the crypto firm, according to a May 8 statement from the SEC. SEC Commissioner Caroline Crenshaw blasted the pending deal in a May 8 statement, saying it would damage the regulators’ ability to keep crypto firms in line and undermine the court’s ruling. Source: James Filan “This settlement, alongside the programmatic disassembly of the SEC’s crypto enforcement program, does a tremendous disservi…

Crypto exchange Coinbase’s total revenue fell 10% quarter-over-quarter to $2 billion in Q1, missing industry estimates by 4.1% as trading activity slowed across the market. Coinbase’s net income was sliced by 95% from a near-company record $1.29 billion in Q4 to $66 million, in a large part due to Coinbase marking a $596 million paper loss on its crypto holdings. The firm’s earnings per share of $1.94, however, managed to beat the Zacks Consensus Estimate of $1.85 for the quarter. Coinbase’s May 8 results also showed that transaction revenue fell 18.9% quarter-on-quarter to $1.26 billion, as did trading volumes, which dipped 10.5% to $393 billion as crypto market cap dropped by double digits over the quarter, partly attributed to the Trump administration’s tariffs.  In contrast, US Presi…

🚨 𝗪𝗔𝗥𝗡𝗜𝗡𝗚: Your Agile team might be losing productivity without you realizing it! The big problem? CONTEXT SWITCHING. Here's what studies say about context switching: According to the American Psychological Association, switching tasks can cost up to 40% of your productive time. A study by Gloria Mark, a professor at the University of California, Irvine, found that it takes an average of 23 minutes and 15 seconds to regain focus after an interruption. According to psychologist Gerald Weinberg, each extra task you switch between eats up 20–80% of your productivity: For agile teams, this means: So, how can you fix this?

In the quiet corners of recording studios, a technological storm is brewing. Artificial intelligence, capable of replicating the unique timbres and resonant qualities of human speech, promises innovation—but brings with it profound ethical challenges.

Together, let’s step carefully into this nuanced landscape—where the human voice and machine capability meet, mix, and inevitably conflict. For voice performers, their instrument isn’t merely technical or professional. It's deeply personal: a distinctive signature inseparable from their identity.

Hi Dev.to, I'm Dylan Clément, a full-stack developer and designer. Over the last few months I’ve been working on something called Jolyo, a web platform built specifically for indie game developers who are tired of juggling a million tools. Like many in the game dev scene, I found myself constantly switching between Trello for tasks, Notion for docs, Google Drive for assets, Discord for team chat, and itch.io for visibility. It worked, sort of. But it was messy and inefficient. So I started building Jolyo, a platform that brings all these essentials together in one place, with game creators in mind. Jolyo is a web-based workspace for managing game development projects. It centralizes everything: tasks, documentation, team collaboration, and community sharing. Instead of jumping between disc…  ( 4 min )

Mastering Git from the inside out—what every developer should know. Git isn’t just a version control system—it’s a content-addressable key-value store with an elegant and powerful object model. Understanding this model enables advanced usage, more efficient workflows, and better debugging.

Git’s internal model revolves around four object types: Type Purpose blob Stores raw file content (not filename). tree Represents directory structure. commit Points to a tree and includes metadata and parent commits. tag Creates referenceable, named points in histo…  ( 4 min )

In the Go programming language, we often see the use of the underscore (_), such as using it as a placeholder to ignore unwanted variables, importing packages solely for their side effects, or ignoring variables in type conversions. However, most people may not have encountered the use of an underscore within a struct—specifically, defining a struct field named _. So, what is the purpose of defining such a field? _) Fields First, let's look at an example of a struct without an underscore (_) field.

PARSER combinators are widely used in the world of functional programming, and OCaml's Angstrom library is one of them. It is used to implement many foundational parsers in the OCaml ecosystem, eg HTTP parsers for the httpaf stack. However, one of their bigger downsides is the lack of accurate parse error reporting. Let's take a look. Suppose you want to parse records of this format: 1 Bob ie an ID number followed by one or more spaces, followed by an alphabetic word (a name). Here's a basic Angstrom parser for this: open Angstrom type person = { id : int; name : string; } let sp = skip_many1 (char ' ') let word = take_while1 (function 'A' .. 'Z' |'a'..'z' -> true | _ -> false) let num = take_while1 (function '0'..'9' -> true | _ -> false) let person = let+ id = num and+ _ = sp an…  ( 4 min )

When developing an Angular application, managing multiple asynchronous initialization tasks can be a bit tricky, especially when you need to chain them to ensure all required configurations are loaded before your app starts. In this post, we’ll explore how to properly set up multiple app initializers in an Angular 19 application, specifically when using the provideAppInitializer function to load configurations from a service. Understanding App Initialization in Angular Angular's dependency injection system provides a way to delay the app's bootstrap process until all necessary dependencies are ready. This is done through the application configurator, where you can specify initial functions to execute before the application begins. For instance, in your application, you have provideAppIniti…  ( 4 min )

Lazy loading is a technique that can greatly improve website performance, especially for pages with a lot of content or images. Instead of loading all elements of a page on initial load, lazy loading allows the browser to only load elements that are visible to the user, saving bandwidth and speeding up page load times. As users increasingly rely on mobile devices and sometimes slower internet connections, site performance becomes crucial for user experience. One of the easiest ways to improve performance is by using lazy loading for images or other elements that are not immediately visible on the page. One way to implement lazy loading is by using the Intersection Observer API, which provides an efficient way to detect when elements come into the user's viewport. Here’s a simple example of…  ( 4 min )

Unlocking Git’s Inner Mechanics for Expert-Level Mastery When most developers think of Git, version control comes to mind. But beneath its porcelain surface lies a powerful, content-addressable file system designed with immutability, integrity, and efficiency in mind. This post peels back the layers to explore Git as a content management system, powered by cryptographic hashing and a robust object model. At the core of Git is content-addressability—a paradigm where content is identified and retrieved using a SHA-1 hash, not a filename. “If two pieces of content are the same, Git ensures they are stored once—immutably and efficiently.” This design guarantees: Uniqueness: Identical content results in identical hashes. Integrity: Any mutation alters the hash and creates a new object. Dedupl…  ( 5 min )

In modern web development, creating a dynamic user interface with interactive elements is crucial. One common use case is the contenteditable attribute, which allows users to edit text directly in a block element. In this article, we'll address a specific challenge: how to change the color of certain characters while still allowing users to type freely in a contenteditable div. Understanding the Problem The issue arises from the way you are manipulating the inner HTML of the contenteditable div. When you use innerHTML to replace characters with styled elements, it effectively refreshes the entire content of the div, causing the cursor position to reset and leading to a frustrating user experience. This can also prevent users from typing, as they may lose their current input context.…  ( 4 min )

In the world of databases, ensuring data integrity and consistency is paramount. This is where ACID principles come into play. ACID stands for Atomicity, Consistency, Isolation, and Durability, and these principles are foundational to any SQL database operation. Let's explore each principle and provide examples to illustrate how they work in practice. What Are the ACID Principles? Atomicity Atomicity ensures that a series of database operations either fully complete or do not happen at all. This means that if one operation in the transaction fails, all previous operations are rolled back to maintain the state before the transaction began. For example, consider a banking application where we need to transfer funds from one account to another. Both deduction from the sender's account and add…  ( 5 min )

What I Learned During the SheFi Program — And Why I Recommend It I started my journey into the world of crypto with a lot of doubts. I thought: "If anything, I’d invest in ETH, not Bitcoin." But even then, I was concerned about the environmental impact. Reading more, I discovered that Ethereum had transitioned to a more sustainable consensus mechanism — Proof of Stake (PoS) — unlike Bitcoin's Proof of Work (PoW). That helped ease my conscience a bit. But that was just the first hurdle. I set up my wallet and opened an account on a crypto exchange. That part was fairly smooth — I'm a software engineer, so I know my way around tech. Still, I found myself uneasy about usability and safety. Crypto addresses are long, unreadable strings, and one wrong character could mean losing your funds fo…  ( 4 min )

Introduction If you're writing a simple text editor in C and encountering issues with your text disappearing when using the Backspace key at the beginning of a line, you're not alone. Many newcomers face unexpected behavior in their text manipulation functions. This article will dive into why this happens, particularly focusing on how Backspace interacts with your cursor position and text storage. Understanding the Issue In your C text editor code, when you press the Backspace key (ASCII 8), you're performing different operations depending on the cursor's current position. If the cursor is at the beginning of a line (cursor_x = 0), the function tries to merge the current line with the preceding line using strcat. Though this is an intended feature, it inadvertently leads to the upper line …  ( 5 min )

Did you know you can create dynamic routes in Next.js with just four lines of code? As a freelancer working on front-end projects to pay the bills (thanks, American healthcare system), I recently discovered how to create dynamic routes in Next.js without any extra complications. The Problem I was tasked with creating a list of dashboards for Annual Performance Reviews (APR). Each APR has a unique name, and each one needs its own route, like: http://localhost:3000/apr/[ReviewType] With a large dataset containing various types of APRs, manually creating each route by making individual folders inside the app directory wasn’t feasible: -- app Manually replacing review[index].type with the actual review types from my data would be tedious and inefficient. The Solution I simplified the structure by creating a single folder: -- app Using square brackets in a folder name creates what Next.js calls a Dynamic Segment. With a Dynamic Segment, you can access all the parameters using the useRouter hook. In my case, I didn’t need to use the hook because I already had the review types, and the slugs in the URL matched those types. The solution was straightforward: const reviewType = reviewsType.find((rt) => rt.slug === params.reviewType); The {params} are the props in the page.jsx file of my Dynamic Route. If the reviewType from the URL matches the slug type, it’s a valid reviewType, and I can create the slug. It’s that simple. Later, I'll call the Links with their href destination to generate the user’s click in the sidebar component: reviewsType.map((rt) => {rt.title} ); Conclusion Next.js routing is incredibly powerful and easy to use.

Cloud platforms are built to scale. That’s their core feature — and their hidden risk. Every request to a cloud function, database, or storage API has a cost. If enough requests arrive, even legitimate-looking ones, the backend will scale automatically and incur that cost — and the account owner will receive the bill. This is not an exception. It is the intended behavior. Several public cases illustrate how cloud billing can be exploited or spiral out of control: $100K in 24 hours via Firebase – A WebGL hosting app saw a sudden traffic spike and was billed over $100,000. The cloud service scaled perfectly. No failure occurred — other than financial. One public file in Firebase = $98K – A single shared file led to massive egress usage and a near six-figure bill. GCP DDoS → $100K+ pro…  ( 4 min )
